I would say it is important to adjust the accidentals within the music, as some appear beneath the note, often being quite confusing to read. Of course this won't be a problem if the musician is reading the tablature, but still it must be corrected.
I do quite like it, but it doesn't feel really that bluesy to me. Is sounds quite pop-ish in is essence, while a blues guitarist soloes over it, which isn't bad at all.
Perhaps studying isn't the only route. I find that in the popular culture, listening and playing is often more important. As a fusion guitarist, I often studied improvisation, and blues players would mostly study improvisation only. I mean, at least the ones in the past, maybe not anymore.
Also, if you haven't done it yet, please listen to Steve Morse. He is a "virtuoso of the virtuosos", and is quite a great composer. He implements counterpoint into his music quite a lot, while still sounding really like blues/rock'n'roll.
