i think you just need to make it more nice to look at and more going on
ill be honest with ya..to me it just looks like stadium with carew and young slapped on with some text in the corner..sorry lol
you should try some brushing and create a nice sort of atmosphere to the background and maybe try loads of things in the background over the stadium pic and just on the whole make it more interesting
heres an example of what i mean
