You need to start with basic anatomy and proportions. Study real human figures and apply that knowledge to your comic characters. Also, learn about different shading and inking techniques to add depth and texture.
One example is a series of drawings showing a day in the life of a farmer. You can see the farmer waking up at dawn, going to the fields, taking care of the animals, and then coming back home at sunset. Another example could be the story of a superhero. The pencil art might show the superhero's origin, like getting special powers, and then using those powers to fight villains in different scenes.
The key to mastering manga drawing is a combination of consistent practice, learning from pros, and having a passion for it. Pay attention to details, experiment with styles, and don't be afraid to make mistakes - that's how you improve!
