The biggest thing that stood out to me was the drums. The kick pattern is too busy. Simplify it. The quality of the kick doesn't sound too good, imo. I'd layer it with another to make sound beefier
The snare doesn't hit hard enough and has way too much high frequencies in it. Replace it, layer it with another, and/or compress it.
The hat is good but the pattern sounds like something out a trap beat with the rolls. Also I'd lower the level of that bell some too.
Yeah man the melody is good. Boombap's all about the drum brother. Once you fix those you'll be straight
And can you feed me back? Peace
