I recently completed the rainbow character drawing challenge where you draw one character from each color of the rainbow.
Red: Caine (The Amazing Digital Circus)
Orange: Bingo Heeler (Bluey)
Yellow: Pompompurin (Sanrio)
Green: Tsuyu Asui/Froppy (My Hero Academia)
Blue: Oshawott (Pokémon)
Purple: Amity Blight (The Owl House)
Pink: Angel Dust (Hazbin Hotel)
Let me know which one is your favorite.
