Members of NoCA have an exhibit up in the foyer of the O'Neill Library in North Cambridge, as a way of promoting their work and their upcoming winter show. I have two pieces (below), a collage and a watercolor both based on the same photo of Central Park in fall.
Watercolor: "I Recall (Central Park in Fall)"
Note that I used similar elements in each--the buildings in the background, the stone bridge (although with a different placement), the water, the red tree in the foreground. In the collage, I populated the park with two people enjoying the view from their Adirondack chairs, adding a more playful feel.
Collage: "Autumn Serenade"
