For those afraid of same-face/body syndrome or who just want to make sure they've achieved some style consistency for their characters (should close similarity be your aim).
Pick three characters (preferably of the same species/body plan) and draw the body part or shape asked. If you want to compare more, just copy the rows and add more.
DO NOT USE COLOR. Either draw with ONE color or black throughout the whole piece (until told otherwise) or use one color per character (example: red for char1, blue for char2).
When told to draw the Shadow of a character, it's asking for the silhouette. If you don't know what a silhouette is, google it.
Memes done! (if you're not added here, it's either because I'm lazy, I'm behind, or you didn't follow the meme's rules)
