I love the lighting you have going. You might have to add more light for the character though when they get in there. With compression the lighting might pixelate alot of the movies -- or maybe not . Looks great so far.
I love that you are still working hard on a scene that I would have thought finished until I see you newest version. It's looking great. I can't wait until you finish the whole thing.
I don't think you can go wrong with listening to the seggestions of R_Reynolds. I am really not an expert at modeling mechanical. For close up views you will definately need to take the advice of the experts. For longer views I think it looks vine. Especially if it's painted black.
Looking real good so far. Are you using porcelain? I use it all the time now. It's great for getting rid of the little lumps and bumps that are just too hard to get rid of.
