i definitely like the background idea and how it looks. good job there.
as you said, the text could use work. to me, it just looks like its hanging there in midair. a lot of people will add smaller text underneath for some depth. maybe like Phoenix Suns or Number 1 etc... i would also suggest throwing another layer underneath and moving it slightly to the right or left of the orange text. it gives it an outline look that can really help. also, many people dont think to do it, but you can use different lighting on the text too.
the big pic of amare which is the focus seems kinda boring to me. a smiling amare just standing there isnt all that exciting
also, id tweak the cutting around amare's head on both sides. you can sorta see the outline of the previous pic (i think. unless thats an intential outline or something)
