The drums sound stock fl studio. Melodies are very nice keep them up. Supersaws are weak. Bass feels a bit off. Whole track is quiet. Research mastering techniques for stock fl studio plugins. It will help you a lot. So keep at it and you will keep improving. Also for dubstep, I recommend the plugin, Serum, or Massive. Serum is easier to learn though. You could probably find a crack if you don't have the money. Fl studio harmor is works well too along with sytrus. Just research how to make dubstep basses with them. Also get the free plugin OTT. USE THIS ON EVERYTHING. Although I would lower the depth to around 30% on most sounds, then drag the middle bars slightly to the right until it sounds better than before. I also sometimes change the downward to 80%. Also add risers to the buildups. I suggest researching free samplepacks. I got free cymatics sample packs which are usually paid off of a site called fls audio. I hope you take this feedback and improve because this took a long time to type up.
