A DnB song i've been working on
tell me if the melody is to repetitive or something to make it better

It's nice! It's ok if the melody is a bit repetitive in much of DnB, because you can make up for it with effects and complex drum patterns. After listening to hundreds upon hundreds of DnB songs, I came to this general conclusion: what works best is usually
a) a complex beat with lots of breaks, mixed in with samples and chopped (or sometimes un-chopped) vocals with a simple melody (sometimes almost non-existant) and a nice leading bass OR
b) a really nice melody with a lot fewer effects and generally a simplified beat and bass pattern.
Obviously, take all that with a grain of salt, as I am by no means a music expert; this is just taken from my personal listening experience and the experience I've gained from making a good number of DnB songs myself. Keep up the good work! :)
