I'm really amazed by both your creativity and your attitude to making music! :D Keep it up and treat it like some sort of hobby/passion and don't be scared to learn new things :)) But now some advice - I'd recommend you few things: first one is EQ. Some parts of your song sound a bit muddy like your saw, I think they could be cut somewhere (layering might also help to get more juicy sounds) Don't be afraid to cut frequencies because you will get much cleaner sound if you layer for example with different types of saws (if you wanna get good on some mixing, layering, etc. you should totally visit Jay Eskar's youtube channel as he makes fantastic videos about making your music sound interesting and cleaner. For example "How to make your drop sound huge" or something like this is really really helpful. You can learn a lot from him!). And as we are talking about interestingness of your song I felt like it's a bit repetitive and because of that - a bit boring (I know it's a preview but I still think adding some ambiences, soundscapes, etc. could really do a great job). Colouring your song with some ambiences can really add a lot of vibe into your stuff and also make it more memorisable and of course - interesting :) Cymatics have a lot of packs with ambiences/atmospheres so you should definitely check them out! :D
Overall I really like the fact that you added some juicy sound effects like some plucks or whatever that is in the drop breaks :D Also the creativity and the overall idea is pretty juicy but as I said try to make it even juicier with these tips!
I also remembered now one thing I actually found out :o Making some sort of "counter melodies" (you can google them up for more detalic info) is a really good way of making your track even less repetitive! Use your main melody on the drop or the most intensifying parts, while use a different melody that will have the vibe of the song in it, on intro, verse, etc.
But as I said it's really good, keep up the good work on your stuff and stay as positive as you are! :D Great job!!!
