That was nice for an intro to a song or something, but if you keep repeating it during 4 minutes, it will become boring.
You need to come along with something stronger that makes the song have a rush, and then, you will have a good structure.
Thanks for the criticism bro. I made this in about 1-2 hrs and the main focus was supposed to be on the guitar which does change even though it's rooted in the same key.
Thanks for taking the time to reply though! I'll probably be re-doing this at some point as I really enjoy my the base of its structure and idea.
