Right off the bat, I really don't like that piano hammering on the same note. It's obviously synthy. When it drops out, it's also a little excessive feeling. What follows is some pretty lit DnB. This is the style I prefer, honestly. Sax and piano could have gone far, far, away during that drop, and I would have been very happy.
The writing and FX on the piano after are not bad by any means other than a little bit of corny synth business. The piano and sax just feel like they should be much less present in the drop and a lot more ethereal, panned around, or w/e as an effect rather than a center piece.
The more subdued verse is not bad by any means, and they don't stick out here. I had hoped for a 3rd drop. That bass though – a marvel. Superb. Rest needs fine-tuning.
