Hey mate i see no ones helping you out here so ill see if i can give u some advice
ok so the drums sound a bit repetitive mabye try layering another beat over them thats a bit different.
the bass lines not bad but again mabye a little repetitive and id try n get a nice sub to fit under that.
i like nice atmospheres in my drum n bass so you could try and add a pad just to make it more intresting... but i do like the drone at the start sounds cool.
i imagine this is one of your first tracks so dont feel shit that it aint perfect just keep trying man, im pretty new to this aswell so i aint no expert, good attempt.
