Hi, I like the idea, the sound, nice melody and I really appreciate your effort. Well done. I just would like to suggest some improvements of tune editing/mixing etc.
First part of the tune is very strong and there is a lot of passion. When start beats at time 1:04, you are playing more deep notes and some fast licks above. Bass needs more volume here, because low notes sounds always quietly. Try to focus on dynamic of your right hand as well. Long notes are strong, but fast notes are so drowned sometimes. (the same apply when you repeat at 2:40). Slap backing line with drums at 1:36 is cool, sounds surprising at the right moment. Maybe the starting solo melody is a bit loud for a few seconds. Don´t be afraid of making the support slap bass more distinct. The good way as to do it, is simple. Just turn the slap bass panorama slightly to the side. This will make two bass lines a bit separated from one direction. Especially end of tune from 3:20 needs this panorama separation.
Keep up the interesting work, I´m fan of the way, how you thinking about bass lines. I used to make it similar way....
