A believable smile is more than just lifted mouth corners. The orbicularis oculi muscle compresses the eye area, creating the squint that makes a smile feel genuine. At the same time, several other muscles move and shape the mouth. #anatomy #characterdesign #3dmodeling
The back of the ear has two main forms – a pizza crust edge and a cone connecting to the head. Watch Uldis block out these volumes in the full video tutorial on YouTube: youtu.be/i97e-VnJxUM?...

Ears don’t just wrinkle with age, they grow. On average, ear length increases by about 0.22 mm per year, adding up to nearly 1 cm over 50 years. Most of this change shows in the earlobe. So if you're creating an older character, make the ears longer! #anatomy #3dmodeling #characterdesign
Starting with the contour, we define the helix and then carve into the concha. But that's just a small part of it – watch our full ear sculpting video on YouTube! www.youtube.com/@anatomy4scu...

Nasal aging is a structural shift – as the nasal tip descends, the cartilages separate, causing the nose to gradually increase in length and size. An important consideration when creating older characters. #anatomy #characterdesign #3dmodeling
Early eye aging is driven by decreasing orbital fat. When character designers depict this, they need to keep in mind that as volume thins, tear troughs deepen, eyebags become more pronounced, and the orbital rim becomes exposed as a bony landmark. #anatomy #3dmodeling #characterdesign
In youthful faces, superficial and deep fat is evenly distributed and held in place by facial retaining ligaments. As we age, these ligaments lose their firmness, causing the fat layers to shift and droop. This changes the structure and proportions of the face. #anatomy #3dmodeling #characterdesign
The ear is tricky to sculpt because of all its complex curves and folds. For character design, understanding its true volume and structure is key, and these 3D model cross-sections break it down slice by slice. #anatomy #3dmodeling #characterdesign
We’re finally doing it – A4S video tutorials are here! Our new free Sculpting the Head course just launched on YouTube. Start from a sphere and follow Uldis step by step to sculpt a realistic head. New videos drop twice a week – subscribe and sculpt along: youtu.be/HB1G8gXfdxU?...
When you bend your finger, the top stays angular while the bottom becomes rounded. That’s because the top is shaped by bone, while the underside is padded with soft fat. That contrast is key for sculpting realistic hand gestures. #anatomy #3dmodeling #characterdesign
The scalene muscles are three pairs of muscles on each side of your neck. They run from your neck vertebrae down to your first two ribs. These muscles help move your head and neck – tilting, turning, and bending it forward. #anatomy #3dmodeling #characterdesign
When the head rotates, the SCM shifts so the line between its start and end points forms a 90° angle against the horizontal plane. It's important for artists to understand this anatomy when designing or animating their characters. #anatomy #3dmodeling #characterdesign
When the neck extends and the head tilts back, the trapezius does most of the heavy lifting. Meanwhile, the cervical vertebrae hinge with a huge range – up to 85°. Great to know for character artists aiming to create believable neck motion. #anatomy #3dmodeling #characterdesign
The two heads of the gastrocnemius muscle create the calf’s outer and inner curves – rounder and lower on the inside, tighter and higher on the outside. Together, they form the diamond shape of the calf. A must-know shape for character artists and anyone studying anatomy for art.
The gastrocnemius is the main surface muscle of the calf. It merges with the Achilles tendon, which inserts into the heel. Remember this when sculpting, drawing, or modeling the lower leg. #anatomy #3dmodeling #characterdesign
Male buttocks feature less fat pads than female ones, making the base forms more angular. When simplified, they can be blocked out using two short cylinders angled outward – use this approach whether you're #3dmodeling, sculpting, or studying #anatomy for art. #characterdesign
Meet the bony landmarks of the knee: medial and lateral femoral epicondyles, patella, medial and lateral tibial condyles, fibular head, and tibial tuberosity. Also clearly visible on the lower leg is the medial surface of the tibia.
Bony landmarks define the surface forms of the knee – where bones, muscles, tendons, ligaments, and fat pads meet. They're useful for anyone learning anatomy for art. #anatomy #3dmodeling #characterdesign
When the leg is straight, the fat pad behind the knee sticks out. Bend the leg, and the back of the knee sinks while the calf bulges. The calf also pops when the foot extends – a must-know tip for #3dmodeling , #characterdesign, and anyone studying #anatomy for art.
If you saw our earlier male torso cross sections, you’ll notice the difference here – the female forms are softer, more fluid. These cross sections help character designers shape more believable female bodies. #anatomy #characterdesign #3dmodeling
Let’s start with the basics: the thorax and pelvis. Then, more complex forms are developed on these fundamental movable masses. Whether you’re sculpting, 3D modeling, or studying anatomy for character design — this one’s for you.

Mastering the hand isn’t easy, but breaking it into simple shapes helps – especially if you’re into digital sculpting, 3D character design, or just studying anatomy for your art. Check out this breakdown from block-outs to organic forms! #anatomy #3dmodeling #characterdesign
The hand is made up of 27 bones. Carpals, metacarpals, and three types of phalanges: proximal, intermediate, and distal. All color-coded for clarity and built for artists studying #anatomy, #3Dmodeling, or #characterdesign (with knuckles in all the right places).

Surprise expression engages the frontalis and depressor labii inferioris muscles – lifting the brows, widening the eyes, and dropping the jaw. This anatomy breakdown helps 3D artists and sculptors study expression in detail, from surface forms to muscles. #anatomy #3dmodeling #characterdesign
Recognize this pose from our new book cover? The self-hug pose compresses and stretches muscles in the chest, shoulder, back, and arm, showcasing how surface forms shift with movement. #anatomy #3dmodeling #characterdesign
Scapula (Shoulder blade) for artists
A flat, roughly triangular bone that moves with the arm, altering the visible shapes of the shoulder and upper back. Its spine and edges are the visible bony landmarks. #anatomy #scultping #characterdesign #3dmodeling
The eye area color-coded block-out doesn’t follow strict anatomical boundaries – instead, it’s mainly based on differences in form. It makes it easier to read the structure, highlighting key elements like the eyelids, tear bag, brow area, etc. #anatomy #3dmodeling #characterdesign
