Since you asked...
The toes a bit glossed together, one wasn't even "capped", the colors slide past the borders of them (mostly the right one), and the right foot is oddly shaped for the angel we see it as, and the ankle isn't too well defined (I would have normally let that slide, but the left foot shows that you can do better detailing - this I think is a result of using pastel from the back to the front, and it should have been done the other way).
The ribs coming together is slightly off center and should be a bit more defined where they at the bottom. The tops of the breast have a hard line going out from them at different angles that also seems to be a border for the colors being different and not slowly transitioning. The nipples so be a bit more aligned with each other (now visually, both breasts should be the same size, but to be correct, having them slighting different is what you should do - and did do). And in the clavicle, the jugular notch should be a bit visible, but only because you have made the clavicle itself defined.
Most of the shading makes it look like the light is coming from above but the shadow cast by the right leg seems to have a different rule.
only issue i have is lack of face. other than that prety decent.
thanks for feedback.
