I'd love one.
It needs to have a darker scheme to match with my avatar. Emo, blood, but simple. Not overdone.
Your choice with the renderer, the images, basically everything.
If you don't do well on your own, I can refer you to some samples, but really whatever works.
Oh, and for size it should be a rectangle... maybe double the width as the height at least. It needs to look good horizontally.
