Through the use of highlights/bright colours, the focal point is established in the bottom left corner of the page. The landscape is a mix of darker cool tones, with little deviation. Everything, from the sky to the land, is laid out to accentuate the high contrast of the moon. The light bouncing off of it is reflected onto the surrounding grass and trees, establishing their proximity to the focal point. This perspective makes the foreground obvious since everything past the moon is too small to realistically be “close”.

The diagonal edge of the cliff creates a clear divide between the foreground and the distant background. Past this, the piece can be naturally broken up into layers.

The flat farmlands have their own distinct colour and shape. Past that, the dark green of the mountains, with their organic shapes, appears as a separate layer. It splits to the blue mountains further back, and then up to the sky.
Each of these sections has distinct characteristics, which causes the brain to organize them into layers.
