Damn, you got that 9th style covered. Maybe create another drum pattern 2 for every couple of bars for a switch. A bass line woudlnt hurt. The only problem I see is signtaure sound. It sounds too much like 9th. That's why I stopped studying him. I wanted to keep my own identity. Its hot though no doubt especially for the rapper "looking for a 9th beat"

Also maybe do another pattern with that sample but chop it differently for a switch. So in the end you have two sample patterns and two drum patterns. This way its not just a repetetive loop. Your chops are real good and it sounds very soulful. Beats must motivate the soul for a rapper and this does. I know everybody who raps in my immediate circle would wanna spit on it.
