I'm really happy with how this turned out! It was the most enjoyable commission I've had in a while - so great to have a nice, big photo so I can see all the yummy details.
For the child's skin, I used an H2 pencil, very light shading smoothed with a tissue to create that porcelain-like baby skin. (Darn you, babies! I want your skin!) For the mother's skin, I used a technique called "circulism," which is basically drawing lots of tiny circles on top of each other. This gave it a slightly more porous, freckled appearance. (You can't really see it that much in the scan, however.)
Thanks for the order, Casey! I hope you like your drawing.
