Avoid excessive clutter and over-detailing in the composition, which could overwhelm the viewer. Steer clear of overly saturated colors that may result in a garish or disorganized appearance. Avoid unrealistic or impractical poses that detract from the character's visual appeal. Ensure that the lighting and camera lens effects do not create distracting or unintended visual distortions. Keep the illustration coherent and legible, even at different resolutions.
