Composition: I placed the colors that were similar to each other as far away from each other as possible, and created movement by placing lines for the eye to follow.
Thumbnail sketch: A thumbnail sketch is a small-scale drawing of your composition. A viewfinder helped decide which part of the composition to draw.
3D: I placed objects behind one another and made cast shadows to show dimension.
Light source: I placed highlights on the feathers where the light struck and used the direction of the shadows to create a light source.
