Hey there!
I like it a lot:
it's simple, effective, and loops perfectly.
bass part is like the coolest ever: no show off in here...
drums are also cool...ezdrummer you say? never tried this one...sounds good...
I would've wanted to have something longer, with more variations,
beacause hear you can clearly hear that you have gotten
all you could out of those thirty seconds and two chords progression....
but hey...i guess you aware of all that, so I'll just cheer you for this great loop...
peace
