bruh i aint gonna lie u got a decent number of things to improve on, i recommend u do some research just google shyt about producing just start off with how to produce hip hop, ur drums are on point but the mixing isnt up to par i cant rly list all the things to improve just look up how to mix, also ur melody is extremely quiet
tbh this type of stuff is subjective, i could see someone really liking it i wouldnt say its bad, im assuming you are adding more beat changes/bridges/chorus to this
tbh for a beat app this is good idk how much more you can do with the tablet
