Mouse-overs:

I don't think the beige background on the drawings page fits the theme of your site. Beige/khaki is traditionally a "casual" color, whereas your line implies dress and formality. As an alternative, I suggest having the background black with the background behind the images white. Upon a user mouse-overing, I suggest making the focused image have a white background and the others a dark-grey background (or a dark-grey translucent foreground). Try to stick with the neutrals or bold colors; they indicate that you mean business.
