Are you planning to model more Yu-Gi-Oh monsters? I've been importing characters into Mario Kart Wii and there a a number of Yu-Gi-Oh monsters I want to import so if you are planning to model more I would be particulary interested
Is that triangle limit referring to the character with or without the veichle? If it's 2000 triangles (btw, a triangle is half of a face, so 1000 faces is 2000 triangles) making the model will be a challenge only if the kart is included, otherwise it would be pretty easy.
Also, I'm planning to make the Exodia model later this year as a project for my academy, so stay in touch!
