That was amazing, but here are somethings you can improve!
1-The transition at 0:10(Almost) was weird for me, i suggest using a fade-in sound effect or automate the volume of that arp thing from low to high (you know what i mean xD i can not explain it that well huh).
Everything else before the drop was good and the buildup was well done(also ear catching) ...but
2- I am not a big fan of the drop to be honest, especially the first synth that the drop starts with
(maybe it will sound better if you moved it 1 octave down?) the rhythm was good but the synths are just so high in pitch in my opinion ,try bringing them 1 or 2 octaves down for each synth and figure out what sounds best to you :3.
(oh it is the same issue for the second drop too :v)
everything else was great,all instruments were going well together,the melody was nice,and the beat was simple but not bad.
you mentioned you are not the best at dubstep,but who knows? you may become!
keep doing your best! looking forward to hear from you again :D
