This is a very attractive approach to a project . the problems of color are greatly reduced, the lighting is dramatic in a Noir-ish way, and it reminds me of the 30's and 40's Universal Horror movies. Looking at this, i can see the possibilities of using pain's gray, and maybe one of the cool tones : cobalt blue, as well as black . also, the traditional approach of a burn umber, or burn sienna underpainting could also be used , as well as artist's pen, in a Gustave Dore derivative . also, the reflected lights could be utilized in a different way from full color, without compromising the 3 dimensional look. very appealing as an art project in it's own right. It took me years to be able to use color without the attendant discomfort that comes from the psychological effect of color on the artist ( attacking reds, retreating blues, and contrast in cool and warm hues.) a lot of my work contains TOO many colors, so, as an alternative approach, this could be very enjoyable . BRAVO !
