How to effectively depict something in the past in a comic?

Well, to draw darkness in a comic, start by using a lot of black. Maybe add some deep shadows and limit the amount of light. Also, think about the mood you want to convey - is it creepy or mysterious? That'll affect how you show the darkness.

You'd need to show the scene realistically but also handle it sensitively. Maybe focus on the build-up and the consequences rather than the act itself.

Well, for a bomb siren in a comic, you could draw it as a huge, circular object with red and yellow lights swirling around. Make the sound lines coming out of it thick and jagged to show the intensity. Also, have the characters covering their ears or running away to emphasize the danger.

A good way could be by showing the internal struggles and emotions through detailed expressions and thought bubbles. Also, using a somber color palette can set the mood.

Well, to describe past events in a comic strip, you could start with a character reminiscing and then show the event through panels. Add some dialogue or thought bubbles to explain what happened. Also, use visual cues like faded colors or sepia tones to indicate it's the past.

To comic yourself, try imagining yourself as a character in a story. Consider what kind of poses, expressions, and colors would best represent you. Also, look at examples of other comic characters for inspiration and adapt those ideas to your own self-portrait.

You can show nodding by simply drawing the character's head moving up and down slightly.

You can start by showing real interactions and shared experiences between the friends. Make their conversations and actions feel genuine.

You can show stuttering by having the character pause and repeat certain words or syllables. Make it seem natural and not overdone.

You can show it through the character's expressions and body language. Like, having them wince or hold their injured part tightly.
