Here I present a really nice illustration from the story "The Lost River", which was featured in the rarely-seen four story She-Ra Ladybird compilation book. I love the way in which the background is rendered in this piece. The characters once again are rendered with an outline around them, much like an animation cel, making them stand out. However, the background is really noteworthy, with a beautiful rock formation next to the water. The waterfall itself looks impressive with an iridescent green color scheme striking the water as it flows over the ledge and down below.
