I don't want the image to have an excessively bright or dark exposure that affects the visibility of the details in the illustration.
I don't want the image to have overly dramatic or artificial lighting that distracts from the serenity and beauty of the scene.
I don't want the image to have a forced perspective that distorts the proportions of the angel, the animals, or the garden.
I don't want the image to have excessive editing that makes the illustration look unreal or far from the watercolor technique.
I don't want the image to be poorly focused that makes details in the artwork appear blurry or out of focus.
