First of all I like it though there are some parts that are not quite good. At first listening anyone can notice the brass (or whatever it was). It just sounds kinda generic. Try another instrument or make this instrument complete synth (think it would sound better). The second and most importatnt part is the fast ending in the piano... I mean c'mon can't you add something else to extend it a little? Some more instruments (more strings, woodwinds, drums)? I give it 4/5 because there's future in this melody and hope that you can make it better.
Sorry dude, but it's Work in Progress... that explains the heavy speed ending.
But thanks for the review, I'll work on the brass.
EDIT: Replaced the brass with flutes
