Its a really nice song for your first dubstep! (comparing to mine first dubstep lmao). The first thing I would recommend is to get stronger drums. And don't make the cymbals too loud. They are there just for the background like white noise. There is too much stuff going on in the drop, too many growls playing over eachother. Try to make a simple and cool bassline first and then put some arp or reaaally simple melody into the background (don't make it too loud). You can also use a short pause between build-up and drop which can be filled with drumz, predrop vocals or just silence. Its a great way to add an impact to your drop!
I like that this track is really clean, its not loud af and even if its messy, i can hear all the sounds. I like that in the second part of drop you switched to drum n bass beat which gives the drop a lot more hype at the end.
overall, for me its honest 6/10. I love the track but there is still a lot to learn. Keep up the great work!! (sorry for late reply)
