Bkg doesnt suit the theme. Doesnt look good for my likes.
i mean the bkg doesnt make any sense regarding the theme itself.. so its just a bunch of things you threw to the bkg. sorry but thats my feedback.
My advice, try add things that are kinda related to the theme, something like the ball itself fainted behind, stadium, fans, refs, etc.. dont just make rectangles with dashes.. doesnt make sense, if you know what i mean?
Keep it up, just clear your mind and you will do a better sig imo.
