Just as a note, I did criticize him for messing up my elbow, nose, and eyebrows :p
also i told him he made my nipples too high and pointy even for my larger size xD
Art isn't usually meant to look realistic. This is impressionist. The elbow is exaggerating the proportions, but so are the full breasts and rear end so why aren't you saying they're messed up too

I can't see the thumb on the left hand but I guess it's the angle.
Is a nice drawing he's real good.
