Determine the characteristics of monsters, refer to photos or images, practice drawing skills, create background stories, and try many times.

1. Determine the characteristics of monsters: monsters have strange appearance, behaviors or abilities, and determining the characteristics of monsters can be better drawn.

2, reference photos or images: unfamiliar with a monster, you can refer to some photos or images for inspiration.

3. Practice drawing skills: Monsters need some complicated drawing skills, such as shadows, perspective and details. Practicing these skills can draw monsters better.

4. Create a background story: The monster has a background story, such as how it appeared and what its purpose is. Creating a background story can better understand the monster and draw it better.

5. Try many times: the first attempt will not succeed, but you can constantly improve and improve after trying many times.
