Give Grookey a more angular head with accented downward facing cheeks. Think boomerang but obviously not as thin. You could even make that yellow mask stand out more by making it look like it's not flesh to the face.
Change Scorbunny's eyes, lower his forehead. Make those cheeks stand out and give shape.
Make Sobble more droopy, puffy rounded cheeks. Lumps are your friend.
