I like the composition, sounds very old-skool as mentioned above. A few remarks regarding the mix :
-
drums have to be louider (at least kick and snare, percussion is okay)
-
I would probably invest a lot of work into the drums and make the bass more sublte (perhaps a sub sine with a few saws on the mid range, but not as the most prominent instrument)
Nice to hear innovative dnb here (advanced dnb producers often are much too housey for my taste, at least you wanted to bring the old spirit back instead of jump on the tech house/pseudo dnb (mostly liquid) bandwaggon.
