It never really goes anywhere. There is no substancial build-up in the percussion or any of the main melodies.
It starts to get a little more interesting passed the first minute and a half, but it still needs a lot of work. The pad you have going in the background in the latter half of the song should have been changed and edited a little more, it sounds a little boring.
Anyways, i have no idea whether youve improved or not as i havent heard your other songs.
I will do so now though :3
