Make sure you post it here, allright?
Hope it all works out well for you, man...
Hey, you really are a Petrucci freak, aren't you?
I've listened to the other clips of yours on Soundclick and all are very well performed, but I somehow feel that Overture was recorded first, am I right? You might as well change your nick to "Seasoned Drewski"
Like Chris said, your bends and vibratos are really "seasoned", not the usual very stiff sounding stuff with jerky vibratos you can mostly hear from average hard practicing budding guitarists. That's easily heard in Satriani's Always With Me... you put on Soundclick. Most of them manage to reach certain speed, even clarity in their playing, but God forbid that they rest on some half note or even whole note...
Besides the right practice regime, you seem to have the feel for the guitar itself, that's why I'd like to hear some of your own stuff.
