Take a blur tool and go over the edges of the picture, and it wouldent hurt to make a new layer and add some brushes over the picture gently so it blends well. Add some color and it will look better.
Now, knowing your a idiot you will probably say "HAHA THAT WILL MAKE IT SO CRAP", why? because your a tosser. Judging from the last post i tried 2 help you.
