sounds like a really long loop

it has a good potential, but it just seems to be the same loop.

you should try addin some effects, or having a two part main beat.

the main beat you have currently is good though. i'm also a fan of slowly added beats. but IMO you should have 2, and when you go back to the original, have a new beat that is a bit different then this current one.
3/5, sorry dude, but it's what i feel. HUGE potential though.
