Explanation: During the rock climbing activity, the muscles on the person’s body change inconsistently in size and definition—sometimes appearing exaggerated and pronounced, then fading or becoming shallow. This is unrealistic, as muscles should maintain a consistent appearance in terms of tone and definition, reflecting stable physical form throughout the activity.
The fluctuation in muscle size and definition is not natural, as muscles should retain a steady appearance without extreme size or color changes during movement. For realistic representation, the muscle tone should be consistent and proportionate to the person’s form, only adjusting subtly as expected in physical exertion.
