Not bad
I hate to be a wet blanket, but I didn't really like the original tune. The melody just isn't really something I ever got into, but honestly I like this one better. Pure-Metal is a good guy and he did a great job with the guitar work, as I would have expected. The cover parts you did sound great, and a lot like the melody, just in your own style. I've tried to do cover songs in the past and I know it's not easy, so props on that.
Not much else to say really, like I said this tune was never really my cup of tea, but you did a fantastic job recreating it and putting your own spin on it. It looks like your effort really paid off. The mixing seems right on, and the guitar doesn't overpower the main melody. Good work with this, keep it up.
