Mario,

Terrific work with the WC! Well played. Musical.
Nice guitar work, too.
Good levels on everything.
Those Swam instruments sure sound good.

During the early part when the sax is the lead instrument, I thought it should be mixed a bit more towards center (like slightly-left-of-center). I felt the same way when the guitar became the lead instrument - that it was panned too hard right. Thought that would benefit from being slightly-right-of-center. Although when they were trading-licks, that panning worked. (Even then, I think having the two slightly panned would work, though you might want to increase the panning at that point to some degree for more separation). Opinions, of course.
(and NOT to detract from how nice the playing is...)

Cool stuff.
