Cool intro! I like the piano, but try to fade the piano and the melody (also the piano :P) seperately in :) so you don't start with a chaotic song.
I like the drop, but where is the bassline? the hi-hat sound to loud in my opinion, actually it sounds shrill (maybe an EQ or master problem?)
And when you make a second melody, stay with the chords (maybe another sound) and make the melody from scratch, the it sounds more unique and people will more likely listen to your songs
