Hmmm

The intro dragged on way too long, in my opnioion, could've used a heavier bass kick, or maybe an added synth after a few seconds of your original intro, but :58 seconds of a 1:26 song being the intro, yea lol. Granted this says a preview so...

Also after the drop at :58, it's a bit hard to grasp the beat you were aiming for for a second, though after a second I caught on, not bad but with a beat that eratic, you probably should've loaded a longer preview.

All in all, for your first attempt, and from this sample, not bad, you'll get the hang of it ^_^
