Really need some help with my my Baron Davis sig...

[hokiefan011]

Started on this last night, and tried working on it for an hour or two today, but I can't think of anything else to do with this. So, I came to ask some of the best for some ideas...

Different style, I know. BTW, this is my second sig ever so please don't bombard me with criticism. I'm wanting to become a full-time GFX guy, so I'm hoping to learn from some of the best around to be the best that I can be...

Bottom right is very empty...
