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.
Depicting darkness in a comic involves several techniques. You could play with thick, bold lines to create a sense of heaviness. Or use gradients of black and grey to give depth. And don't forget about the placement of light - a single source of light can make the surrounding area seem even darker.
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.
You can use sepia tones or faded colors to give that past feel. Also, old-fashioned clothing and hairstyles for the characters can help.
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.
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.
Well, to show movement in comics, think about the direction and flow. Use panels to sequence the action. And don't forget to add speed lines or afterimages for impact. Another tip is to vary the size and shape of the figures to imply motion.
