Source a cartoon figure for each of your group's emotion words.
Trace its outline and fill with a solid colour. You can either do this IRL and scan the results or use a graphics program such as Photoshop of Illustrator. Erase the original (If a scan).
Viriana -- whilst it's great to see you making original things... this exercise actually asked you to find cartoon characters and turn THEM into silhouettes...
okay here's this!
i had trouble with "optimistic" since i only own comics about depressed people, apparently
i showed the original panels too, for context - i hope that's alright
