I listened this track again and again and here are my feedback:
- verses: i like the idea but maybe it would be better if you play it in a funkier way, almost ternary.
- 1.08 - 1.18: i think this riff has to be soft, maybe it doesn't need slap bass?
-2.21 - 2.43: same
-3.25 - 3.46: same
Anyway your groove is awsome :)
