The song seems confused. It's trying to be both exciting (techno), and peaceful (piano). Stick to one and you'll be fine.
I vote go for peaceful. It's not usual that we see a successful peaceful piano part in NAP. To do this, I'd suggest:
Keystrokes at 0:36 needs to be toned down. Drums at 0:41 are neither useful or useless. Choose to either incorporate it into the end of the song (tying it back to the beginning) or cut it entirely. You need to tone down the techno at 1:21 (either decrease the volume dramatically, or cut it out entirely - I'd do the latter). It detracts from the piano.
Overall: Piano wants to be the centerpiece. If you want it to be excitng, use the piano as an accent instead of the center melody. If you want it to be peaceful, tone down the techno side of it.
8 Stars; 4/5.
