I normally don't flip the image horizontally because it looks weird, but I might do it this time sweatdrop
That's exactly why you should do it, lol. A good picture should look good both ways, I think. When I flip my pictures, they often tend to be leaning even though they seemed normal when I originally drew them... And if they're leaning when they're flipped, it means the original position is also leaning.
The eyes are definitely a problem. Just tilt your head to match how her head is tilted and it will probably be pretty clear (the eye to our left is too high). I think I'd have the eyes lower overall with the angle her head is on, though.
With that angle, the top/back of her head maybe seems a bit cut off... or maybe it's just too round at the upper-left part of her head.
Her breast to our left appears to be smaller than the other one.
And what Thaliat Everwood said about the shoulder.
The eyes are the main problem; otherwise, it looks amazing overall.
