With color this time, based on round island boas. Pencil first, then digital coloring.

Something in his design (that isn't noticeable in my drawing) is what I've heard called a "dovetail" chest - the costal cartilage by the ribs is uneven and sticks out more on the left side (his left), while it's sunken in on the right. The muscles around that area feel off sometimes, and he has to take time to "uncoil" (before I even thought of a snakesona, that's the term I always used). Exercises help, and he has a nice heating blanket to wrap around the area.
