Like Mardy said, BG needs more depth to it cause it's quite plain at the moment. The small render looks odd so different placement could help. Try adding some textures too and change up text.
lol I just noticed that small render once u said it.| It looks meaningless there.| Its missing some flare which I get looking at the render you chose.|
V3 is the best so far...I like the coloring and texture, but I think more detail should be added in the emtpy spots of the back ground.Also, the "de la hoya" text, I don't like. See if you can change that up. (keep the oscar text)EDIT: o ya...don't forget to put a BBW or bballworld.us somewhere
IMO the bg is fine. It would look weird with more stuff in it, would look more cluttered than it need to be. The de la hoya text imo is better than the oscar text. But hey it's all up to you.
