Reply to First ever track!! Comments and feedback?

Hey guys!

I just finished making my first track ever using Ableton. I did this whole thing today and just want some feedback on how I can improve? Please feel free to say whatever comes to mind (if it's s%#t let me know too lol) and also offer constructive criticism.

Cheers!
