I wouldn't call it "failing miserably" -- it's not bad at all. But you asked for feedback so:
- The low end seems weak. The kick in particular has a nice "click" but really needs a low-end thump. You could layer a sub bass over the bass, and maybe distort or saturate the bass a bit to give it more presence.
- Some of the mixing seems off, the little 3-note melody gets too loud sometimes and overwhelms the mix (like at 3:30).
- The vocal samples sound grating and too loud sometimes. (2:10, 3:05)
- The whole thing needs more reverb, and I think mixing with some reverb and frequency cuts would help the issue with the high melody and the vocals.
- Arrangement: I like the slow buildup although it needs some subtle things going on at the beginning. I like the break at 2:25 although it's really simple. Since the track continues with the same melodies for 3 minutes after that, I think it needs a change or another break.
I'll answer specific questions if you have an idea of what's wrong... I like the basic groove and melody, though. It's kind of a chilled deep house vibe, like something for the end of a DJ set. With some minor mixing work it could be great.
