I like your original koi posted. good choice. see the black in the dorsal? that will appear later to surface on the back itself and create what is referred to as a "saddle" an important component to stabile the pattern.
Joel Burkhardt at pan intercorp has a nozomi koi show in june and Omosako's 2nd son is coming to talk about their shiro's. For people in the pacific NW will be something you'll want to get to. Lots of info on pan's web site.
