This is the first one we did. It's a still life using only black, white, and gray.
Another still life. This one we got to choose the objects. I decided to make it hard for myself by picking a book (the bible), watermelon, quarters, my wallet wrapped in tinfoil, all over a mirror.

The assignment on this one was to fill each square with a different color, texture, etc. so that none of them looked the same. It was more of an exercise in color mixing, but turned out cool regardless.
This one's painted on a gesso-ed wooden board. The assigment was to paint something entirely using a palette knife. I painted from a spot in the Bard cemetery. It took much time and frustration, but I think it turned out well.
This one I made just for fun. It's of space.
