Loses beat when the drums kick in
I get the feeling that you just threw a bunch of loops together over a recording of you trodding away on the piano, but I'll try to ignore that...
Anyways, the introduction led me to believe that this was either to turn into a meaningful ballad about a man's sad life, with the piano growing more complex as the song progressed, or it'd turn into a song ridden with obnoxious drums and beats. Sadly, this turned out to be the latter.
Anyways, as I said, the piano sort of sounded lost when everything else came barging in. It's like the meter changed completely. Now, that's not a bad thing, but in the context of this song, it is. It's like when you're driving and there's a ledge on the road about a couple inches high, so when you go over it you get bumped a bit, and a bit annoyed, but no real damage is done. Try keeping the flow you established in the beginning throughout the entire piece, maybe?
And another thing, this felt pretty much like a collage of loops, blips and samples. That's not a bad thing either, but you can't go around doing this forever. Unless you're Girl Talk, or Daft Punk which you're not. You're you, and as a creator of music, you need to actually do things to what you're working with. Introduce melodies and harmonies in the piece. Diversify. Complicate. Stuff like that.
Anyway overall, the song is alright, I guess. The vocal samples were a nice touch.
