Art Help On How To Make My Graphics Better

[Cat]

I would really like to know what you guys think of these grahpics. Some of them you have already seen me use as Sigs and avatars but I want to know how to get better. I'm not at the level I want to be. I use GIMP so that you can give me some tips in what i can do to become better at that program. Thank you very much for taking the time to look at my graphics. Some of the graphics on here I made for my MyOtaku site.
