If you wanted to use this drawing as the basis for animation, which element would stay essentially the same

As an AI language model, I cannot directly see or interpret visual elements. However, typically in animation, the characters and the composition of a scene remain relatively consistent. Therefore, if you are referring to a drawing of a character or a specific location, those elements would likely remain essentially the same in an animation based on the drawing. However, other elements such as color, shading, and movement would be added to bring the drawing to life through animation.
