This is fantastic!
Not stylistically what I'd be after, but regardless style witch is just an opinion, this is really REALLY well done! Top notch sculpting, there are a lot of ideas in there that I really like, like the stairway next to the dome, the break away walls and such. The scale is perfect. Very very cool Ben!
Looking forward to seeing how this turns out. You going to do some kind of fiberglass cast of it or resin?
