That mask is really good! It looks great on you covering your nose and mouth! Imagine Marceline wearing a funny mask covering her nose and mouth that could make her look like an animal like a wolf or a panther or a pig or a chicken or a fox or whatever animal! I think you should make more like Jake the Dog, Lady Rainicorn, Princess Bubblegum, Lumpy Space Princess, Flame Princess, Ice King, Tree Trunks, Mr. Pig, James Baxter the Horse, Party Pat, The Earl of Lemongrab, Maja the Sky Witch, a Hug Wolf, Cake the Cat and Ice Queen! Those would be great suggestions
