Hi,
first of all:
for a piece from imagination in general and even compared to your earlier imaginative drawings this is awesome!
That said, I am still not happy with the face…(as if that counted, but you asked for it:D)
Maybe, what is disturbing me might be the same thing which is has been giving you a hard time drawing that face, namely the fact that it is not clear what her emotions are in that particular moment?
Is she just plain desperate?
furious?
turned on? (forgive me - I somehow had to ask this as there is a slight sexual nuance of dominance in this composition:D)
fearful?
I think you get what I mean. Maybe if you clarify her emotion the expression will be clearer and the face in general stronger.
Just my two cents…
still inspired by your drive, man!
