the second one isnt bad. but the left side seems too empty. and the third one i dont like the effects at all sorry.
second one is best like birel said, it looks too empty as of now. Might try just adding text with a little effect there? The third one seems weird to me :/ is that white stuff part of the render or is it some kind of abstract? To me it's just part of a stock you used instead of a render
this one pwnz hard.. one of the best ive seen here perhaps.. yeah its a bit empty on the left but imo text around that area and uve got urself a winner.. great work mate
