The melody was nice and I kinda liked the feel of it. It sounded like the samples you used where of really low quality though. The structure is pretty good and the percussion is really nice :D.
One tip: Try giving your songs an interesting name and always uploqd an icon for it. When people see a huge list of songs in the audio portal, what usually makes them click on a song is that the song has an interesting name or an interesting icon.

Don't give up on newgrounds just yet :). If you just get a bit more involved with the community you will surely receive more feedback.
