Hmm... I just noticed something weird with her left leg (Her left... not the vewers')... it seems to attempt to go down on the right side (Vewers' right) of the water-bottle while on the top of the knee it extends left (Vewers' left)...
It looks as if you tried to extend the leg down but decided to go left instead... what is that?
I have no way of really knowing, but often times adding the colors to his works puts it in context. If he eventually puts of the finished version we may very well find out what the leg is supposed to look like.
Love the pose, the musclutaur is excellently done as well. She's got the pumped look that you see stronger people get just after working out.The design of the glasses also is well done, it reminds me of the old civil war era style glasses, where string or bits of wire where used to keep the spectacles on someone's face.
