Dislike the tempo, minor key and lack of surprises
I'm not too keen on the scales you use. I just don't like the switch early on - it sounds odd to my ears and almost like it's been done for no reason.
Also, the voice seems slightly off-beat at a couple of moments when coupled with those beats. I got used to it after a few listens, but really reckon you maybe should've changed up the beats somehow. I think you matched up the tempo as well as you could with a steady loop for the beat, but it does sound a bit odd.
When the extra melody comes in around 1:30, it's quite cool. I really like that 'tinkling' kinda sound. However, I reckon the scale of the bg bass should switch back into a major key.
Another complaint is that for the most part, the changes you bring in are kinda obvious, and there really aren't any surprises or any cool little twists. It's quite a 'by-the-numbers' thing.

There are a few cool instrumental bits, but the minor key gravitation and the lack of interesting variations put me off.
