Experimental is fine, but yeah, it can be hard to pull off. Redg manages to pull it off:
However, in this case, I do agree with @Cubeshark that this is a bit too sparse. You may want to add something to fill in the gaps, like a glitched drum loop to add interest, a pad to create some sort of tonal filler, or a bass to glue the mix together. Near the end of the mix, the glassy pad you had was doing that job.
Something else you may want to consider is finding a structure; I typically want to be able to skip 15 seconds forward and notice a forward change in something, whether it's faster hi hats, more bass, less drums, etc., rather than just a change. Something where you can tell whether you're in an intro, a "chorus", a breakdown section, an outtro, etc.
