| Segment | Approx. Length (as % of total arm length) | Visual Cue | |---------|-------------------------------------------|------------| | | ~ 30 % | Long, tapered shaft, deltoid “cap” at proximal end. | | Elbow to wrist (radius + ulna) | ~ 35 % | Slight curvature on the dorsal side; radius is slightly shorter than ulna. | | Wrist to tip of middle finger | ~ 35 % | Hand length roughly equals forearm length in most adult proportions. | | Finger phalanges | P1 ≈ 0.4 × hand length, P2 ≈ 0.3, P3 ≈ 0.2 | Shortening toward the tip helps keep the hand compact. |
If you want to take your digital or traditional sculpting further, let me know:
Render tendons as slightly raised, tapered ridges with a subtle “pinching” at their insertion points. Lightly incising (or carving) a shallow groove alongside a tendon can accentuate the illusion of a cord under tension.
