I like it, and i know its a preview but heres what i have to say.
So far nothing is really wrong with it, but its a little thin. Theres alot of room for sounds to fit in and sound really good with tehis template you;ve thrown in.
I think you could make more use of that weird effect you are using, and actually give it a musical importance. I went through the whole loop expecting it to do that, but it never happened.
Try instrument stacking on the bassline more if you aren't going to add any extra parts.
The beat could be a bit heavier at parts, and maybe add a bit more punch to the downbeats a well.
at 27, i think the melody line could use a bit of echo.
Good start though, look foward to seeing the rest.
