This just goes to show... if you don't play ANY sound idiomatically, the sample quality becomes moot. Playing piano or organ licks on a sax or harmonica sound is going to make it sound naff.

And I rather wish he'd played through the variations... The smoothness of transitions from one sector to another is often the telling point in a style. Do they progress naturally? Do the fills join them smoothly? Is there any weirdness in style voices as it jumps to the new section (or fill)?

All in all, as presented, seems a push to me...
