Pretty awesome cover, I liked your vibrato during the solo.

One thing I'd say is that the vocalist should probably put more effort in. Sounds like he's singing what he's supposed to but he's not really feeling it.

I dig it. Sounded really good to me. If I were to nitpick I'd say the vocals sounded a little shakey a couple times but nothing major. Really nice job mixing that all together.
