There are some artists that you'd think pure light was coming out of their pencil instead of graphite, based on how well they capture the palette of light.
Noah is one of those artists.
Look at each of these pastel paintings, and study how he lights the scene(s) to convey the mood he's going for. It's captured perfectly. Plus, his designs are incredibly unique. A little over-stylized for my taste, but in terms of color and light, I'm a big fan.
