Hard to completely review a song that isn't complete, but I'll review with my impressions so far :)

It has an interesting build up; sort of a spacey ethnic vibe. This is more of a video gamey feel than a "radio listen". When it finally kicks in at 46 seconds I think the toms could use more punch. Not sure if it's the EQing or the samples you used? I think another element that could pull the listener in to the new section are some pads or added instruments. My ears feel that section has a lot of unused space.

In its current state it leaves me wanting to hear more which is a good start. Overall it's going in the right direction, but i'll need to hear more. I'll have to listen to the finished product. Keep at it!
