The atmosphere in the Museum of Modern Art was very tranquil

The atmosphere in the Museum of Modern Art was very tranquil, the lights aren’t too bright, and the wall itself looked like a piece of artwork. I’d been walking around the museum for a while and I finally saw a piece of painting that was what I’d been expecting to find.

It looks nice, it makes her hat stand out very much.
