Fantastic stuff. Glad I stumbled across you- albeit late into the game. Based on your works I can see you've poured a substantial amount of time into anatomy and that is something I always appreciate in an artist. Despite the character being fictional, you still have to deal with the suspense of disbelief and one of the surest routes to accomplish this is understanding inverse kinematics and physical limitations/interactions.
Thanks for sharing. I'll be keeping an eye out for more of your work.
