You should not have a fifty second intro to start a three minute track. I was tired of hearing that trumpet by the time that the beat dropped. The first eight seconds were great to start with, but hearing such agressive, high-pitched trumpet blows really catches the listenener off guard so quick into the track. I'm sure something as simple as volume control could help ease the punch that the trumpet is throwing. Also, at forty seconds, the sample that you chop and repeat is at such a slow tempo that it reminded of a Family Guy skit where Peter keeps repeating an action until a commercial comes on.

I like the idea of sampling a sound like this to make a hip-hop instrumental, but I strongly encourage you to spend more time on it, and not to overpower the track by doing too much. Especially since the first few seconds of the song make an impression of being slow, calm, shut-your-eyes music.

Just remember this is only my opinion, and it honestly does not count for much.
