I love that you're experimenting with color. It not only adds more data about the leaves you're comparing, it also really brings the images to life, as if you've invited the readers along on your outing. I have a watercolor set but I still haven't dipped a brush into it. Seeing your work is really making me want to try adding color to my descriptions. Thanks!
Wow, I need a lot of practice. It's really helpful to see everyone's sketches here and compare different approaches. I'm not yet patient enough to try stippling, but scribbling is definitely right up my alley. I'll need to grab some veggies from our CSA share and get to work drawing them. Thanks to everyone who posted -- I aspire to get my produce to look as lovely as yours!
