Interesting...
Initial comments: You seem to be new to this. That's ok, don't worry about that. You're experimenting, which is a critical step in getting better. Don't take the rating personally, either - I see potential here, so I'll help you if I can.
Flow: There's a bit too much repitition. I think you can probably hear that for yourself. The 3 seconds that keep looping do have a sort of flow of their own, which is good. But the whole piece doesn't have flow. It doesn't go anywhere or serve any musical purpose. There needs to be something done to make more rhythmical and harmonic variation.
Also, watch the transition from back to front of the loop - the loop doesn't finish the phrase before it begins again. You might want to fix that, or just keep it in mind for next time.
Balance: Decent, although you really only had one voice and a couple background effects going on to deal with. Nonetheless, I think that the balance present is still pretty good. Your mastering is actually fairly acceptable overall.
Effects: Not too much going on, but I like what I do hear. You seem to understand a few interesting little effects and how to use them.
Themes: No themes were really present. Throw in some melodies and variations, and some other voices or instruments... and you might have something in the way of themes. You have a nice atmosphere, though.
Extra: None.
Overall: [3.84/10.00]. Needs some practice, but you have the ability to get yourself places. Keep experimenting and getting better! :D
