Hi.
Good job on the remix, if this is your first one, it sounds a lot better than my first. The good thing is that the overall idea or theme sounds nice. The melody that you put behind a trap beat works and definitely has a groove. So, the core of the song is solid, which is the most important thing. The bad news is that your sounds need work, and then after that, your mix.
This is trap music, so the bass is very important. If I were you, I would really make the bass pop out a little more. Put some horn farts or other powerful midbass on top of a deep subass to give it depth. Listen to what some of your favorite trap tracks do and just copy their bass. At this stage of your career, just flat out copy other people's sounds and use them in your own compositions - there is no shame in that. Copying well is the mark of a great artist.
The main melodic sounds are also a little flat. Round them out some more. Again, listen to some souonds that your fav trap artists use and go for those. There is definitely a "general midi" flimsy feel to the sounds that takes away from the song.
Beyond that, there are some problems with the mix, but what I mentioned before is more important, so first correct these problems and then solve some problems with the mix. By mix, I mean, panning, EQ and effects. Post another version of this and I will give some feedback on "the mix".
Good luck to you!
