Mini painting!

I painted an itty bitty painting! This is a color sketch for my third painting in the tulip series. I've already had a couple of people express an interest in buying, which I find amusing. It is well executed, but it's painted on a blank CD sleeve! The actual size of the painted area is 3 1/8 x 2 1/4 inches.

Color detail for the sky is 50% phthalo blue mixed with 50% N6 neutral gray; the ground is 50% magenta + 50% N6 neutral gray. More color detail to come. I need to go paint...
