I really liked that track, especially the synth sound is somewhat new to me, never heard anything similar (fact is I don't listen to trap that much). Where did you get that sound from? Also my second question is which reverb did you use on clap?
In terms of what could be improved, I would go through other hi-hat sounds and maybe add some melody to them as well (pitch them up and/or down). But it's just the issue of taste.
If you would like to check my tracks (signature) and let me know what you think, I would appreciate that a lot.
