Ok i think the bass needs to be there the whole time, or at least a couple of seconds after the beginning. The repetitiveness of the synthesizer could be a good thing if the far-away echo sounds like something solid. Personally, I think the drums should have a little bit more of a punch... a deeper pitch. At the end of your song I noticed a change in the bass-like a different pattern. Keep that going, or at least make the pattern closer to the middle. Remember-good songs have beginnings, middles, and ends. Please don't make an end that doesn't land on a C-that is very very important.
NessbeatsFox is right-not bad for a WIP.
