5x7 inches. Gouache on watercolor paper mounted to ACM board.
 
I got a new "Chartapanel" from Artefex, who specializes in aluminum panels. This was my first time trying it, but I love it! It's so sturdy, and feels so well-made. I will definitely use these panels more in the future. 
 
This was painted at Foothill Regional Park in Windsor California. My girlfriend and I found a nice shady bench that had a lovely little pond in front of it. I enjoyed observing the swaying reeds.
