Although it loops just fine in terms of rhythm, it's a little funky. Interesting track you got here, though.
I quite like what you have here. It's fairly simple, but the slight rhythmic and melodic variations make it rather interesting. I feel it could be mastered to add some significant volume, but it's not so quiet it's unenjoyable right now. (Consider a compressor or a limiter+gain to help pump the levels.)
This has potential. You seem to have the same issue I find with neat loops like this, it's hard to make them into anything that resembles a track. Keep at it and eventually you'll figure out how to get past that road block.
Overall, I like the melody and variations you've put in, but it needs a little more oomph.
