Custom Roof Alt

[madcap3693]

How does this attempt look?

I did it with 3 volumes as specified by the program. Is it OK to have overlapping gutters, when they are at different heights? I assume water would drain down along the wall in between the two lower height roof volumes and run into the the gutter provided.
