The melody and harmony sound interesting and it sounds good! At the same time I think this track could be better! The kick and other stuff going on in the base seem a bit too strong - a lot going on in the low frequencies and I miss the "color" and clarity of the higher frequencies.

The second higher-pitched lead (I think) could perhaps do a bit more movement than going down (what sounds like) a minor 3rd here and there. (It does play a brief melody around 3:00 but perhaps it could do more?)

Maybe also some more reverb and stereo effects....it kinds sounds mono to me. But overall though I think it's a good piece of work!
