Here is a painting I made from observation on the top of Mont Bélair in Canada, just before sunset.
I am painting those in a 5x8 very convenient moleskin watercolor book. I previously eyeballed the dimensions of this book at 4x6 when I had no ruler to verify but I was slightly wrong. Now the info is exact. :)
I've been re-reading the Harry Potter Series, and now am on a quest to do a small illustration for each of the books. This one is from "The Sorcerer's Stone" and features Mrs. Norris, my favorite evil cat.
Illustration painted with watercolors and outlined with pink pen. The borders were achieved with washi tape (low tack and unlikely to tear up your paper.)
