suggestion - use magic wand select open area-- inverse... then use clone tool near edge and redo the ball's edges... that's what I've been doing lately on balls, fingers, and facemasks... it's a good trick
I was suggesting you try it.. but maybe try it on this one as the remainder of the cut is reallly good and should be added to the gallery. sorry for the misunderstanding on the "later" part, as I was thinking you would try to fix later..
