Some of the neatest vertex modelling I have seen $imon, really excellent. I have studied your wireframe image for ages, and I have come to the conclusion that I lack sufficient patience to create anything to this standard! I think, personally, that I like the second last one most, looking as if it has been coated in many, many layers of lacquer. The stark, almost white glare reflections make it clear to the viewer, without any other indication, that there is a window in the wall opposite the one on which the painting hangs. The white light is exactly what you would expect to see through a clear window on a bright but cloudy day, or perhaps through net curtains on a sunny day. My only really minor crit is that I think the shadow cast by the frame is a little too sharp, if the light source is a window. My impression is that it should be so soft as to be almost an ambient occlusion effect, the window being a large, close light source. Really amazing, and although the render is the ultimate point of any 3D work, the wireframe being only a means to an end, it's the wireframe of this work that really blows me away. Kudos mate!
