Quoting Dave Kaleta
Looking good. Don't forget, he's very rich, but it's only for appearances. Maybe make the house audacious and the cave a reflection of his true self. ~Dave
That's the problem I'm having. I can't make the house look as "richy rich" as I want. So I've been looking at examples of mansions, and inner city homes that are on the "Up scale". The cave or bunker will be simple and to the point. I see batman as a "point a leads to point b" As far as a bunker would go. I told myself I wasn't going to make extensive and have crazy levels, and just keep it simple, but if I did that, it'd be a room with a motorcyle. ...maybe I should call this the "bat rest-stop."
And thank you Mr. kaleta for the advice, I appreciate it.
