i know theres a lot, i mean, a LOT of stuff needs to be fixed here, but i think what you need is time, you're a beginner arent ya? don't worry, no one starts off good. Have your time! slowly and surely develop yourself
one thing i'd like to mention doe, pls do fix the chord progression next time :) it sounds very odd here at 02:10, if you have some time, why not watch some music theory video? :)
