It is always a great pleasure to see your work. I happened across an art gallery online that contains many of the 17th century Old Masters---Herr Rembrandt among them---and the similarities in the way you are using light are quite striking. In this gallery, less is definitely more as far as light goes. However in contrast, the detail, color and texture are rich indeed. I experience a sort of tactile response in seeing the different surfaces---the man's hand, the polished wood, even the warmth of the light. Beautiful.
