A great first attempt at riddim. I'm not a riddim producer myself, but this has inspired me to try. Anyway, mixing wise, it's clearly a WIP, so it needs to be improved if you finish the song. The sound design is pretty unique though, and the drums do their job nicely. Overall, I think you should finish it!
Sound Design: 8/10 - It's pretty much unmixed but the sound design is awesome.
Composition: 9/10 - The bass melodies are cool but pretty unclear if you know what I mean. If you make a melody in the full version try to implement it into the drop as a fill or something to add a slight bit of melodic elements.
Atmosphere: ?/10 - Because it's on 14 seconds long this one's too hard to judge.
