Amazing riff that rivals many of the great rock songs of all time. Excellent instrumentation.
The riff is nice and sounds are good. I think what you have played could be a start to a richer song.
It's a cool guitar riff and a great idea for a song. It's a great idea for a chorus or a verse or bridge or a part of a song. I'd love to hear what it becomes once it's finished. It sounds like a recording a guitarist might give a singer to try and write lyrics for. Keep working at it and develop it into something more.
