I stayed back at Biltmore Hotel to practice drawing some architectural elements. Here is a page of sketches the sweeps of brownish color are "free-form" accidents from spilled paint.
The group moved onto Grand Central Market for lunch and outdoor sketching. Some of us went to Central Library for a little more sketching. The sketchbook page below combines the two locations. I enjoyed drawing more architectural details and seeing a park and lush greenery next to highrises.
