Use the Shape Tool and Brush tool in Photoshop to draw a hand-drawn cartoon

Background: Choose a simple background, such as blue representing water or the outline of a home or city.

Water saving scenario: Draw a water saving scenario on the background, where a family is using a tap, but there is a water saver on the tap, or a family member is using a basin to catch water instead of turning on the tap directly.

ICONS and symbols: You can add ICONS or symbols to emphasize the importance of water conservation, such as a water drop icon, a green checkmark, or a text description.

Color and light: Use color and light to enhance your painting. You can use bright colors to draw attention, or use shadows and highlights to add dimension to the painting.

Captions: If necessary, you can add some captions to explain the theme of your painting, such as "Save water, start with me" or "cherish every drop of water."
