Cheers! Really useful feedbackgotchu mate,
whooaaa naughty noises in the intro made me expect something totally different. i really like that 1st part of the build. consider using that nasty growl in your drop! The transition from intro definitely needs some work, it just kind of switches, needs some suspense built in.. maybe consider cutting your drums for build pt. 2 (when that bright lead comes in), then bringing em back in with a kick roll or something?
Your bass elements are hiding way back there on the drop (0:44) the drop lacks impact as well, needs some bass!
With some work you could turn this into a cool rock/dnb hybrid piece mate, just gotta keep pluggin away
