Hi @CBK art, nice studies! Well done constructing the phalanges using simple forms! The perspective looks pretty accurate, though I have a feeling that it would help you to practice drawing boxes and cylinders on their own. The edges of the boxes have a tendency to diverge, and the ellipses on the cylinders are not angled correctly, assuming that you were going for perfect cylinders with circular end caps. Lines that are parallell in reality appear to converge to a common point (vanishing point), and the angle of the ellipses should be perpendicular to the length of the cylinder. If you find it difficult to understand which lines should converge and not, reading this thread might help https://www.proko.com/s/3uw2. In your last post you mentioned "I really struggle with drawing in 3-d " and I just wondered if you've taken the Figure Drawing Fundamentals course or anything equivalent to it? I couldn't see it in your course library. I got into figure drawing because I dreamed of being able to draw Disney's Tarzan. My first thought was to study anatomy and I found proko's anatomy course. Though, since I struggled with gesture and 3D forms, I decided to take the figure drawing course first. And I'm so glad I did! It gave me the ability to draw figures from imagination that looked 3D. And to my surprise they looked quite anatomically accurate eventhough I didn't know anatomy. The figure drawing course is like the anatomy 1 course, so I strongly recommend taking it first. Hope this helps :) Keep up the good work!

Well done on putting in the work, it is getting there. One comment is that your cylinders appear to be in different planes than your end boxes. Look at the bottom L digit. If you placed the distal cylinder into a box, the edges of that box should be parallel. In your illustration, the cylinder is twisted relative to the proximal box
