Let me ask you about these elements.

What do you see as far as implied or represented textures among the subjects? What might they feel like to the touch?

In what form is this work. Is it open or closed? Is it a combination of the two - closed with expanding properties or open with contracting properties?

Is there much depth in this work? What techniques to you see that might make your eyes perceive some dimension of depth? Where and how in the setting does the artist use those techniques.
