What a beutiful Model and nice shot,
I may be in the minority, but I love the negative space on the left side. Giving the Image a different look from normal.
as for Post-Processing, I like the overall softness of the skin but would sharpen the eyes a bit. Also I think a little trimming of her right upper arm with the liquify tool will improve the look of this image a lot.
JMHO....cheers
