I would say the hardest part of this solo is the rhythm. That is probably where your struggle is coming from. It isn't so much that you can't play the licks as it is that you are having trouble with the phrasing. Great open string stuff and bends here.

Simply take it lick by lick, take it slow, and have patience. It will come. But, focus on those rhythms as they are a little tricky. Good luck! :o
