I had a difficult time with this prompt.
Oh, I had plenty of ideas, but they all took lots of time that I didn't have, or even worse, I simply wasn't interested in trying to accomplish them.
Dang it, I said to myself, I want to keep things simple. Then I went 'duh'. That's it. When I grow up, I want to keep things simple. So I did a very simple acrylic painting using Primary Red, Primary Yellow and Primary Cyan on black gesso. I used the negative painting style and painted around the shapes of the trees. It took about 20 minutes. Not my greatest work, but it was satisfying to do.
