I have a number of 30″x24″ panels primed for painting, I love working at this scale. Large enough that you have a sense of freedom moving around the surface but not so large that it is awkward in the studio. I did have to stand on a chair to get far enough away for a photo, so a little awkward!
I am pretty obsessed with brooding epic scenes. I keep getting wound up about new ideas but I realize this is a common thread.
