Excellent use of looping! This is one of my favorite things to do with my instruments! I love the delay you’ve used as well! And that rock tone at the end… nailed it! This is just a personal opinion but maybe you’d like to try using some spiccato in the looped track? I know it’s a ballad but it may help keep the beat and get that rock n roll flavor. Keep on jamming and working on the technical side of things and this will be amazing in no time!
