Needs a lot more work
I'm reluctant to review cause there so little to say about such a short loop, but at the same time I should cause I used the Ad forums.
Its a good a loop and nearly almost semi perfectly loops, well ...kind of. A few post production modifications and you would have had it. You should check out this thread:

Additionally, I recommend you check out the MAC March/Feb 07. You can find the topic in the Audio Forums labeled "Mac7 - March." This loop really isn't that great and you obviously half-assed it. But still even if you don't make better one for the contest you can always submit this one.
Oh yeah... the actual review. I think you could have repeated this and made at least one small variation. Theres some good sounds in here, try a little harder next time and I bet you could make something cool.
Still even a loop this simple works for flash, so good work. And sory, no vote or download for this one.
