i have an incredibly bad feeling about this thread
converse to be honest, i excuse your stupidity since u r not using it against some1 else, but seriously dude, u just fuckin cropped some photos, and that mavs one looks like it was cut from live 04's startup screen
try something special, like shadows, backgrounds, foregroun text, something that makes it stand out
either way, try a steve blake wallpaper or avatar i dont care, see what u can do
EDIT: pic-
