Yeah there is alittle melodic minor in there, because anytime I see a root-7-b7-6-b6 sequence on a minor key somewhere I think of borrowing from the melodic minor. It's easily seen in the first to second chord progression, the first chord Am and the next Cmaj7/G#. I think of Cmaj7/G# as a borrowed III+ chord from the A melodic minor. Also dorian is very closely related to the melodic minor scale, just raise the seventh to a leading tone. A good sub for the dorian scale.
