Not very dNb
When I think of dnb, it has to be 160+ BPM, and very fast with the drums. This song fits more under 'dance', or 'funk'.
The song is well written, and the drrms are catchy, I enjoyed it. Watch the monitor, make sure it isn't touching the red-line too much. If theres nothing but red-line in the song, turn things down! Then put a compressor on the song =) That'll solve your distortion problem.
Good work, keep it up! Could you drop a few reviews on my audio page? I'd appreciate it if you did =D
