Is this a sub warmer?
I like the main idea, but you got some clipping occurring that you really should take care of, around 2:50 it becomes very noticeable. Give the tracks some dynamics, there's no need to have it on the red all the time. This is Audioholics
The LF drone could use some movement, maybe with a LP filter and varying cutoff frequency and Q, or even some rythm.
I also found the rhythm part a bit loud for my taste, I would prefer it more subdued. I liked the beat not being always on time.
This is just me imagining how I would remix your track
