I'd move him over to one of the sides then put some big text on the opposite side. It's not terrible but I'm not really feelen it. It looks weird how you have his face area completely normal but the rest of his body completely blended with the background, like how the center part of his jersey is pure white and the rest is the reddish color. I donno it just doesn't look right to me.
They are barely distinguishable but V3 is the best of the lot, the darker colors at the top and the transition from dark to light has a better effect than any of the others. It's an improvment from the first. Put some text on now.
They are all pretty much the same. These all need some text though. The colors are pretty random too.
