This is good but I don't understand why jazz is a tag. I also think the main melody should have more variety to it. I like the switch up you did in the end, but how it goes back to the original melody is unsatisfying, you should have added something to build up to the change. In the most active parts of the track (
00:24
&
01:48
) the 808 is overpowering the kick which you can fix with EQing or sidechain compression.
