Here is a leaf that I drew a few months ago. I found the leaf on the parking lot and just loved the way it curled and twisted. As I drew it, I experienced every part of it. I took the picture below just a few minutes ago. There is a small part of the longest portion of the leaf which broke off. The drawing is meant to capture the beautiful movement of the leaf, which probably wasn't curled that way while it was still green. As it dried, the leaf on the top left somehow twisted around the middle leaf. The leaf in the bottom does a wonderful lift, then a spiral in the end: almost like a wave. Just lovely. I captured as much as I could in the charcoal drawing. Enjoy.
This is loosely based on the moon. I say that because all the craters aren't exactly where they should be. Also, there are several craters missing. It's not a 100% accurate, but I it works. I used a set of Staedtler pigment liners to get the details down (.01, .03, and .05), then I used a brush with india ink to fill in the dark spots. For the color, I actually used this cheap set of soft pastels that I found Walmart for about $6. I scraped the pastels into a fine power, then used a piece of cloth to wipe in the pigment. I learned that trick from Ms. Hing Wah Hatch from Drawing 101.
