This is so cute! I didn't know that creatures name until now when I had to search up who Walf was lol. The costumes are really cute, I love the idea of Kirby and Walf dressing up for Halloween. The style is also really cute, I love how the color blends on different surfaces to emphasize shading but in patchier ways (like on Walf's shell). The background is also simple but perfect for the picture! Awesome stuff, keep it up :D
