The Cat Returns

Eek, this took a while to do, mainly because I kept doing it wrong and had to rub it out and redraw. Gah. Anyway, as you can probably guess I adore The Cat Returns. It's a brilliant film, and I'm a total Baron fangirl. He's just so gorgeous! In this pic is Haru at the front, The Baron to the right, then the Cat King, Natoru and Natori on the left. I have no idea how to colour this. I want to use my Letraset markers but I'm scared of ruining it. Might get it photocopied first Hope you all like!
EDIT: Baron looks scary without pupils.....
