First off let me say that you did a fine job on this overall and that the flow and feel of the song is very good in of itself. Hard to do better actually. (Brings to mind the great soundtrack of that old N64 title WAVERACE). One thing that I noticed is that the main beat (bass/percussion) seemed to seep into the song a little and made it so that everytime the beat would repeat itself it sounded like the song cuts out for a fraction of a second. Whether this was intentional I do not know, but it just feels like it takes away from the song a bit.
Allow a second or two of silence in the beginning to allow ppl to get ready for the song itself. Don't get me wrong, it starts off quite well, but if this was on someones playlist of their computer or even their iPod it would start pretty quick...takes away a little on the feel.
Nice reverb o.o, it is well placed.
Change up your main beat a bit, all you have is a dum dum dum dum dum dum dum dum....but monotonous. Throw something in like...dum dum dum de-dum (if you get my meaning...hard to explain =\).
The 'clapping' track could, perhaps be made a little louder. It sounds fine the way it is, but since it is so faint it is hard to discern it from the other instruments. Add in what I said for the percussion. Keep the mono for the track but throw in a quick double clap here and there to change it up a bit. I don't know what you work in, but you could send me the file and I could very easily show you what I mean. I dont' expect this...but meh, do what you will.
Your ending isn't bad, but the reverb (?) felt unnecessary. Keep the last note but repeat it and slowly make it softer and softer until it finally goes to nothing. Also add in about one to two seconds at the end to let it finish out. Many artists don't do this...but remember ppl are going to download this simply to listen to it, that second at the end could mean the difference between someone liking it because it allows another track to flow better, to them not liking it simply because it takes another track and throws it on too quickly. Your choice though.
I really don't have anything else to say. Overall your beat was well made and the song itself is quite catchy. In the end its a nice piece of work already, some simple changes can be made, but good nonetheless.
