Swiss chard is very shinny. In this illustration I decided to focus and play with the white highlights on the leafs. Some of the interesting observations I noticed about Swiss chard is that gorgeous pink runs all the way down the stem thought the veins and out to the edges. This pink starts out as an almost fuchsia color and fades in to the center of the stem as a sort of peach tone. Just gorgeous.

In this drawing I’ve included a little set of instructions for drawing a fold or a wrinkle.
1. Draw an S shape.
2. Draw two parallel lines from the top of each arch of the S. One that goes into towards the center of your object and the second also towards the inside should hit the backside of the S.
3. Using a gradient with the lightest highlight on the top of the wrinkle color in the wrinkle. To create the top edge use a value change (a light color up agains a dark color) to imply the edge
