I'm glad you finally found some time to get back at this project.
I really like this build and it would've been a real shame if you'd have abandoned it.
Well when it comes to a paint scheme for this nice gothic built - this immediately comes to my mind
On the other hand even black, with a Boltgun drybrush and then copper/brass/gold trimming and highlighting can be very charming
So, good luck with your color choices - I look forward to see more.
