Portal 2 was inspired by Portal 1, a small acrylic painting for my Portals series. Larger, of course, and similar in layout and colors, it has more detail in the circular form.
Photos of the painting as I was working on it are below.
Title: Portal 2
Size: 16 x 20 inches on canvas
Medium: Acrylic paint
