That's pretty awesome guy! I really like this.
Although, you might have wanted a different snare. Your kick drum is good, it's powerful, but the snare feels less so, and thus, slightly out of place. You probably don't even need a different sample, just add some punch to the snare you got and it should be just fine. There are ways of doing that pretty easy, but it depends on your DAW. Even then though, it's not that big a deal.

Also, it would have been cool if you added the actual moomba beat that you had going on at 0:50 - 0:58 to the wub wub parts, near the end. You know what I mean? Like, if you repeated the part at 4:02 - 4:18 once more, and applied the moomba drum beat to the second part. I think that would have been cool, but what do I know.
