First minute or so was pretty okay, but the shredding/tapping part stumped me, didn't expect it there much - thought you'd stick to your picking etc.
Nice, but imo, I don't think the Vai lick goes really well with the song, sounds pretty sketchy to suddenly run into an 'up-down' kind of motion then back to the 'up' parts again. The part from 0:38 to 0:50 is pretty good, makes the song more powerful though.
Nice effort I guess.
