lol, breasts are nice.

i think the best thing here is the connection of human torso and the snake body. The point where body and snake meet.

if u want sides of her boobies a little bit less creased, probably possible by using "Smooth" in "Sculpt Surfaces Tool" in poly-proxy mode.

but that is your choice. not right or wrong but i think it might look better with lesser crease on sides of boobies. So try that and see if it does look better or not.
