Hi Tim, you gave a lot of effort in this one and even though it's above your level you performed a lot of the blues phrases, especially in the first half, really well.
Your timing was better than I've heard it before as well
This lesson is full of lots of little small bends at the end of a phrase. Often they require you to bend up by just a semitone or sometimes even less. But the idea is that you bend up and then push it higher slightly just before cutting the note of completely. Listen to Sinisa at 0:06 in his version. You can hear how the bend goes slightly higher just before he pulls the finger off the fretboard.
Watch out for the pitch of the bend at 0:44. Notice that Sinisa plays a semitone bend on the first one.
