You did a great job with the arrangement and musical ideas. No critiques there, it has a good sense of energy and flows nicely.

The mix needs work, I feel like the low/mid end is lacking especially compared to the snare which is the only element really thumping. I would say get the kick sounding solid, and mix around that.

The solo at the end sounds pretty good, you could probably nudge some notes to be slightly off the grid a bit more and fine tune the velocity but it sounds good man, definitely something I would love to hear finished.
