This sounds really, really nice. I'm mostly impressed with the dynamics and the mood, which is really spot-on. If there's any issue with this piece, it would be that the tempo, mood, and energy all seem to pick up between the 1:25 mark and the end, and since that's really only about 20 seconds, that's not enough time for you to develop the idea you're playing with. It might have made more sense to make the entire piece more consistent or otherwise develop it into something longer so that the resolution could feel more comfortable.
