I always liked the GBA concept art, but I also like how the artist has changed throughout the years for Fire Emblem. There have been ups and downs for character designs in each game.
BTW, Am I the only one who thinks that Camilla's clothes make her look like a cat because of those thingies in her hair, and twizzle-twins hair makes her look like a rabbit. I'm trying to picture if any of the other characters clothing/ hair makes them look like animals.
