Nice.

first thing noticable is the kick/hat realtionship.
It lacks balance and the hats outweigh the kick.
the kick could do with a little more high end click to balance this, and maybe just a touch more volume.

The bass could be brought up in the mix as mark said it`s not doing much now.
Maybe dirty the bass up just a touch.

There are large gaps in the mix, and although this is minimal, the idea of minimal, is you maximise the little sounds you have to fill the space.
The hats and lead synth dominate, leaving a large gap in the mids, and low mids. Something could be done to fill this space.

A little more variation wouldn`t go amiss in something this minimal either.

Nice overall mood though.
