Congrats on the new venture! I'm sure it's a lot of work. My guess is to keep similar colors together like you mentioned and separate photos for special (markings) ones. No glare of water for more pro look (I don't know how to do that).
The last photo of the spotted wakin looks just like my shubs but with the wakin tail. That is a special one for sure.
