Personally i can't stand linkin park, but I downloaded anyway. The guitarist plays some natural harmonics in that main riff, and you missed those, but otherwise it seemed pretty correct.

The Intro was way off... why can't you count beats? Just listened further, the part before the "shut up" part of the song was off to... How can you think that sounds good, you didn't play it in time.

Otherwise it's ok.
