Nice try ;P
Well, the enthusiasm is there!
First MIDI guitar submission I've heard for this, haha. The kind of guitar sound I had in mind was a warm, bluesy, distorted sound, the kind you'd hear at a dinner jazz club. Your additions, I find, simply do not fit the mood I envisioned.
You introduced a chord progression near the solo section that didn't fit the bassline or piano chords and overwhemed everything else - I could barely hear the rest of the song. Remember when you mentioned that "less is more?" Less would definitely be more in this situation. Silence is a note, too - give the other instruments room to breathe. Pretend that the guitar is a breathing instrument, too - put silence in every once in a while to let it catch its breath. :D
Keep at it, though, the potential is there!
