One of the fun things I always forget about that I can add for characters adds to a more alternative look. Tattoos, piercings, dyed hair.
Simple as they are, they can help round the character out, while giving something fun or exciting to look at from another character’s standpoint. Some, who aren’t as enamored with these sorts of things, may not think of them so much. Others may not have many characters without them.
Putting marks on a character that’s well established already is only tricky if you pass it off as them having it for long enough that it coincides with other works you’ve written. Giving them new ink or piercings, or glasses, or any other small, little things that help aid the appearance, however, can do a lot to sway them in one direction or another, personality wise, or establish their attitude or dynamic better, in some ways.
The prompt/dare is this: Look back on all of your characters and really think about which ones have what. Consider if these things dictate the character, or the other way around. If you don’t have characters with a tattoo, or someone who likes to dye their hair, or has piercings that aren’t in their ears, make one, with the conscious decision on whether the personal affects help define the character, or the other way around.
Don’t be afraid to go overboard, go with what feels right for the character. Write what’s right, essentially. 😉
