They look great A lot more than I could do when I started using photo editing software and your kittys are just too cute!!

Do you have a feather tool on PaintShopPro? It just fades out the edges and softens them a bit... if you select the kittys face, cut it out and then use a small feather radius it will make the edges look less sharp... thats the only thing I can see that you can improve Besides that it's great

And I agree the second one would look great as a piece of fabric....
