Very good!

So what I would say here is try to create direction in your song. Now what do I mean by that? So a song has a start and an end and we have the adventure of getting from the start to the end. It's your job to then create that adventure with what is called a song structure or sections of the song. This can be thought of as parts of the adventure. So in adventure you want to explore because staying in the same area would be quite boring so I would say try not to make the song less repetitive. New places will have different songs but could have familiarity. So the theme of the song can still be there but try to introduce some other instruments maybe. Now for sectioning it off, I would say listen to a song for an example of structures. For an example a dubstep song usually has the start which helps the listener get into the song, the pre-drop to then lead into the drop and then another section that settles down a bit so kind of like a break part and then the pre-drop comes back - but maybe it's a bit different this time in terms of instruments and/or rhythm - and then drop and then ending. That's not how all structures are but that's just an example. I would also recommend trying to find chords to maybe start with and you can try to build off of those and then maybe mix up the chords a bit but that might require a bit of music theory to know what chords work with what. You can also just text to see what sounds good as well but you have to know what "good" even is to you. Overall I would say the take home is:
- Try to add some variety in terms of instruments and rhythm -
- Structure the song a bit better -
I'm not going to mention mix for now as I believe composition is much better atm and you can always work on mixing later.
Have a good day!
