The first three are my copies of examples in Joanne Sharpe's book, The Art of Whimsical Lettering. I love her exuberant color palette and no-fear lettering styles.
This one is original. I googled images for Solomon's temple and abstracted an image.
This one was fun to paint, although I ended up concealing almost all of the text on the waterfall page.
The next one is just watercolor and black ink.
