>>1723856ok thanks, I don't have any resources to help you, but I do the same sort of thing. If you have windows, get paint(dawt)net instead, its free and easier to use than GIMP in my opinion. Once you have it, go to their addons forum and grab things like feathering and anti alias support. Once you have a nice edge you cleaned up with the eraser, use AA assist, and bam, you have a very clean and anti aliased edge that goes onto any background you want well.
you can get paint net for free at getpaint(dawt)net
