Hey! Well..everything can always be improved upon. Lets just talk about the things that stick out most.
The melody completely turns me off immediately, as well as the sound choice. Your other sound choices arent bad though. Also, this is more like a 4x4 beat with a hint of drum variation here and there, just go listen to a DnB track and study the kicks and snares and then just copy that and start from there. Good luck and keep working!
