Not bad.
First thing I noticed was the pad, and I have to say, I dislike it. But eh, minor details, moving on. The piano, sir, lacks effects. I would suggest adding reverb and a tad bit of delay because it sounds too....Fruity Loopy and plain. The high-frequency sounds sound annoying and should be removed IMO.
The kickoff at 0:51 is good, but the beat that follows it totally ruins it due to its weakness, not to mention the ugly (may I say hideous, actually) bass that keeps panning left and right at a volume so high that it manages to drown the other lower frequencies. The melodies themselves are not bad, they're quite upbeat, but again, they're also drowned by the annoying bass and they're too repetitive. The sample choices for the beat aren't that bad really.
After listening to the whole song, I must conclude that the bass totally ruins the song. The song has potential if the tunes and drums are brought out more with some mastering, but it lacks some serious polishing. The pad choices aren't any good to me either, I would suggest better ones. As it is though, the main problem lies on the bass, as I mentioned before. Get rid of that and fix the rest, it could make a good track.
6/10 critical review; 4/5 vote for effort.
