It looks amazing. However, the shading of the body from neck down, or in this case from neck left, looks off when you look at it at this angle and makes the body look bigger and not proportioned. The shading also doesn't clearly show as to which side is the body facing. BUT if you turn the image counter-clockwise (like I did with my laptop lol), it becomes clearer. The top(?) shoulder either looks too big, or just lacks shading.
Other than those points, it's a really nice painting. I absolutely adore how you painted her lips.
