Cheers, been playing 3 years this March. I cant quite get out of using the pentatonic, its just a sound a I am addicted to.

Perhaps it comes from being bought up on old rock which has a bluesy sound.
Dude... You didn't use your pinky once, not once. Practice using your pinky. You are born with 4 digits, use them all.

As far as the playinggoes; not my style but it was pretty decent.
