I have a few wonderful random poppy plants in my garden, and love the virbrant reds and oranges when they bloom. I rush to take photos of them, because the blooms fade and the petals fall so quickly. Here's a photo "posterized" in Photoshop to help me see the larger value shapes.
After experiementing with some fluid acrylis on Tyvek, I created a dead dull mess of a poppy, so I just had to redeem myself a bit, and quickly did a couple of acrylic 8 x 10s to get my groove back. The renderings aren't that great but the colors make me smile.
