I like the flow in this, the pace and melody, but the sound feels way too sharp. Some more ambient instrument/pitch seems to me would sound much better combined with the overall very ambient experience. As for the points you bring up, I like the beginning, it starts off directly, but it still fades in, no fuzz. With a more ambient instrument/pitch, the first time the instrument kicks in it also wouldn't seem so sharp. At times it is a bit slow, maybe speed it up a bit? As for an end, how about a short solo and then just... fade away. This really doesn't sound like house, I'd sort it as Ambient or New Wave, or Experimental/Misc. There are plenty of sub-genres to the existing genres, but listing them all would make it a pain to browse through. Anyway, nice track. Keep it going!
