I am drawn to landscapes with high horizon lines. I'm not sure I can explain why. One of my favorites is Last Light, Tuscany by Salliann Putman. You can get a feeing for her painting style, here, but I can't find a link to that particular painting online. (Drat!)
I tried two, using very similar palettes of indigo, phthalo blue gs, phthalo green, and indian yellow. They are both about 4.5 x 5.5 inches. Even though they have the same palette, they sure have different moods.
