Art My newest graphics

[Cat]

I haven't made graphics in few months. I would like to know what you think of my newest creations. Also I would like to know what I could do to get better. Now I use Gimp because I can't afford the better programs. Two of the graphics are what I'm using as an avatar and signature. Thanks in advance for the help.
