I’ve finally finished working on 3D sculpt based on my own quick sketch. The interesting thing about it is that it was sculpted with no symmetry in the final pose. Below there are several images:
-Painted over version from Photoshop
-Same model rendered with Vray
Turns out that Zbrush rendering is much more fitting for painting over. Vray version looks different. Not sure, if it looks better.
And just to remind, what the original looked like.
