Wow that is one scary lookin thing.
You may have allready covered this, (i first looked at this thread today and didn't have time to read all the posts on it so bear with me) but where is the light coming from. it appears like a spot light from straight on. I think it could look very dreary if you use that lamp as a key light with an oarange/yellow color. and then have some blue coming in from a window on the other side to fill in the rest making the image darker all around but still being quite visible and have a high contrast to really get your attention.
Just a thought. awesome model
