Whoo, this is an old drawing of a couple lineart Pokemon, all of whom have somewhat noticeable differences to what's considered 'normal' for that species of Pokemon: Kirli has a different body shape (counting the skirt) and slightly different proportions, Agash has a more ornate pattern on her shield, handle and tip of her blade and Serin has an extra scale at the tip of his horn and different scale shapes on his body.
