So yeah, I already left a comment on the youtube page about loving how it sounded like something from Samurai Champloo, and I can definitely see the inspirations by Nujabes. Specifically I think it's very akin to 624, Pt. 1, which is one of my favorite tracks on Katana.
I also think the soft male vocals you threw in there was a good way to take the same sort of style as SC and change it up a bit.
Since a lot of people who don't listen to the genre seem to not enjoy the repetitiveness as much as me, there's a couple things I can think of that you might be able to toss in to help were you to have trouble subbing it. Sort of like in Tsurugi no Mai, you could add in some sort of sound clips and background noises to make certain parts seem more busy. On the other end of the spectrum, you could have drop-offs - either the lead or the drum track, or both - in certain sections for some variance.
Personally, I like it just fine as is, but a few small things like that might vary it up enough for people who don't listen to the genre much without forcing you to fundamentally change the song. I'd love to see more of this kinda of stuff from you in the future, regardless of whether or not it gets subbed here.
Also, did you draw the background images for your songs? Cuz those are really great too.
