Cool. I'd have to say as well that this concept creates a cool combo setting that does give a better impression of musicians playing with all the variation.
Something you might want to do to polish this just a little. In the section where the drummer is taking 4's, you will want to move the pan of the guitar slightly left as it is in the other variations, right now it is centered. Also, you might consider totally reworking that guitar part and use legit voicings. Not possible to do piano type voicings like that on a guitar. Also at the beginning during the head, the guitar is not playing authentic guitar voicings.
