I guess you wanted to make a trap drop. In that case, I recommend you to listen to lots of other songs to get inspiration, and to get to know the genre. While doing that you should practise to listen to every single detail of a song. The main issue I heard, but this may be my own opinion, that this track can use a lot more FX, like reverb and delay.

Here are some things that help you to improve your song:
- More bass in the drop
- Variation in the melodies and such
- More layers of instruments (a song becomes more interesting when there is more going on)

Things that are already pretty good (as that is always nice to hear):
- The melody itself was pretty well found
- The intention/structure of the song was clear
- 0:42, that nosy (in a positive way) sound is great

It is interesting to hear such a high quality song made in a rush. Howevah...

Stay awesome,
