Painting Jet's forest always makes me think of what a tragic character he is. Throughout the series, the dominant colors in the episode usually correspond to the nation they are in (the Water Tribe episodes have lots of blue, the Earth Kingdom episodes have lots of brown and green, etc.) but the episode "Jet" stands out because it's so red (Fire Nation) when they're in the Earth Kingdom. In a way it symbolizes how Jet and the Freedom Fighters don't move past their trauma, they live in a forest surrounded by their enemies colors. I think it's an interesting detail.

(The orange and red paint I use for the trees in Jet's forest are called Flame and Dragon's Blood, respectively.)
