Aj. Camille, I've been thinking of what we discussed last time about the way in between "line drawings" & "black & white" which has much contrast so I come up with this one...by adding grey I think it becomes more gradual. This drawing is a sequence of the opening/closing of glass wall and the curtain. Black represents the columns & solid walls,
grey represents ground, and white represents the elements inside the house; for example, toilet seat door & furniture...please give some comments.

Thank you,
Arm
