I illustrated this environment concept art as part of my personal work.
First, I imagined a world and sketched it where each house has its terrain. However, I realized in the coloring stages that you cannot get anywhere with a car. Therefore, I added a plane which felt better for the house to be alone within a large forest. The house was the hero. Hence, I felt this layout made it pop more.
I was influenced by minimalistic illustration, a spark from old-school Looney Toons, and Disney concept art.
