Wow, wonderful for a first attempt. Your skills are great, I'd love to see you do more anthro work in the future.
I'm a huge fan of android based artwork, so I'm quite a fan of this piece.
I hope doesn't bother you by me saying so...but Siku's chest seems too flat, perhaps? Her boobs should likely be lifting/supporting her a bit, and should be somewhat visable. Just thought I'd offer that for possible future pieces in similar poses.
wowowowoow! <3 that just looks beautiful! and awesome yesh, and... first attempt at making anthro? D: that's so amazing x.X i love the expressions and the shading hmmm yesh! and the cybernetic window thing... <3
