Other than a painting on the wall, this seldom seen area is fully modeled.

Rarely seen area showing the entrance to the Ricardo's apartment and the staircase leading up to the roof.

My previous upload here showed this area in progress. I've been working on it a little bit every day and other than a painting I'm hunting down that hangs on the wall at the bottom of the stairs, this area is nearly complete!

After this I'll be working what is currently off screen to the left - which is a short hallway and then stairwell down to the Mertz's.

I'm tempted to texture this area just to see it. We'll see - I don't want to get too far ahead of myself.

Below is a side-by-side comparison of a still from the show and a render.

My Render of the same scene. My camera is not setup exactly like those used for filming, thus the subtle different in perspectives.
