Pretty chill
I wouldn't say this is drum n bass, but more like a breakbeat/ambient or something similar. But there's no category for that, so w/e.
That kick is perfect. The background bass is also raw, and I like that. The only thing I would probably change is the timing of that quieter segment in the middle. It kind of comes in too abrupt in my opinion. Overall, good sound you got going here.
PS. PX9 is a 'she', not a 'he' ;)
