Sketching at Lincoln center

Last Saturday was my first time sketching with the New York Urban sketcher's group. It was great to meet you all in person and sketch along! I was able to make three sketches at the David Rubinstein Atrium cafe. I could not complete the last sketch before we had to move to our next location. I completed it later at home and added a touch of color too.
I also made another double page spread as we sat in the lobby of Alice Tully hall, which I would like to use for the sketch swap.
Here are my sketches from Saturday's meet.
