I like seeing well-rounded poodles, ones that not only have conformation titles, but other titles as well, such as obedience, agility, tracking. And that you as a breeder value these titles as well.
It's nice in addition to the posed winning shots, if you can show action shots of the dogs in competition which show their movement. Of course, videos are great to see their movement.

I'm sure there is more but those are some of the most obvious things. This is a great thread, and I'm keeping notes.
