I think it's a really interesting novel, very complex. However I'm very confused about it's storyform.
Perhaps it has multiple storyforms... I really don't know.
If I had to guess:
OT - The Devil makes mischief in Moscow - Activity
MC - Ivan Ponyrev, young poet - Fixed Attitude
IC - the Master - Situation
RT - A kind of mentor-disciple relationship(?) - Manipulation
