This looks OOF but at this size it is difficult to tell.
Why not post a larger image?
I do think this is not cropped well.
The lower half ends at prominence of bosom, IMO not flattering at all.
Try that exact picture again but crop it at the bottom of the shoulder strap. Also try a very subdued smile with your mouth closed. I think you will have a winner.
The only cropping I did was because the original pic was biger around me..I happen to like the crop on this..but I will take into consideration the other suggestions for the next time I do a self portrait! Thanks everyone!
