The timing of your bends, and possibly even how far you're bending, is a bit off. You're also not playing certain notes as many times as you should be, and there are some more timing issues there as well.

As for the bad-ass sound, it sounds like it has heavy distortion. There might be some other effect being used there, too, but I'm not 100% certain.

you seem t be hitting the right notes for the most part, but its the technique to get the sound. throw some vibrato on with your left hand to get rid of that off tuning sound you have. play with feel and dynamics, the right notes are only part of the battle.
