This sounds really cool! The clean tone is really cool...had an alt rock sound to it.

You asked if it sounded familiar...is the main rhythm similar to Enter Sandman?? I've never played that song, but it was the first thing that came to mind when you asked if it sounded familiar.

There are some variations regarding note choice that you do toward the end that were really cool. As others suggested, if you could introduce some rhythmic variety, it would be really great!

Nice job!
