My daughters just got the most recent official Batcave and it's good fun, but we were thinking of working on something like this. Very inspiring! Loved the Wayne Manor top floor. Would be neat to work in some secret compartments/staircases or other moving parts as well, but you've certainly done an incredible job.
This looks great. I like the different levels you've set up here. The tumbler looks good. Some real architectural genius on this one. The top floor is probably the biggest win in my opinion. Love the wooden look. Very accurate.
