The arm is covered by hair, maybe that's the reason for that. Maybe I should have lowered it a bit.
Anyway, playing with anatomy while creating such monster is really entertaining. :D
I've made a few sketches before taking up this pix, maybe you'll find three of them interesting.
Especially in Naga, I've made the torso longer to include two chests, because arms need chest muscles for proper movement and I believe that its either that way or one has to modify the whole chest muscle concept. Anyway I did not include that in the priestess, just because mates from job, found it too original. xD
I like that kind of characters (i.e. Nagas...).
Even though they are fantasy characters, their anatomy needs to seem believable. It's not just about having multiple arms, the back has to support the endeavor... Something bothers me with the right "upper" shoulder (maybe is it too away from the body?).
Anyways, you did a really great job. Congratulations.
