I never thought of using scaffolding :o Sounds like it would be much easier than using auto-jet...
I'd give a base 5/10, an added one for the idea of scaffolding, and one for the effort. That's 7/10. And one because I luv the window design ^.^ So now it's 8/10. Would've been higher, but I'm not a fan of greyscale color schemes. It looked too eerie, too modern. I honestly liked the warm, inviting coloring on Ephialtes' better. It would be good as a Halloween cottage, though.
My suggestion, use warmer colors. Don't make it look like a spaceship with a fail disguise trying to hide in Medieval times, k?
