There's a lot of reverb on that arp. It's really washing things out, especially because it's sitting right in the midrange with all that reverb all over it. This is primarily a part-writing problem; if you want the arp to take center stage, then keeping it there in the midrange is fine; but if you want to use it as a background element underneath more important melodic lines, get it out of the midrange; bump it up an octave, pull back on the reverb, and lower the volume or velocities of the notes. Consider moving it to another instrument that's not flooding the soundscape with reverb.
I think the arp is a real problem here. The arrangement I like, the DnB is good and I like the instrumentation choices. But that arp is killing me here.
