Amazing painting skills
I won't deny at all your great painting skills dude, they are magnificent, but I'm not completely convinced by the anathomy/fisiology here, her arm is too straight on the borders, no muscle silouete (I didn't really knew how to express that on english, my apologies) and its kinda thin in comparison with the fore arm, her breasts semm to be a little upper than they should, I think that in that position we should be able to see about 2/3 of them instead a half, finally, the thigh vs the hip/leg, the second is too thick in comparison with the first, also I fell that the angle of the leg is a little weird, making it look like the leg it self is short instead of being angled.
The face is gorgeous, and so the elements present in the painting, not to mention grat illumination results and beautiful concept, Congrats!
