Very nice, but... the hand looks very weird. For reference... how many times do YOU stand with your arm at a 90degree angle turned outwards? *looks more like 85, but you get my point.* Anyways, my point is, you might try the poses for yourself before drawing them... You might find they actually hurt. (not really always a matter of flexibility.)

you did a good job the anthrow chest size is right but the limbs may need to be longer to fit the rest of her...i got nothin else to say about it so you're good^_^
