Button and Ducky's colors and markings guide (Ref)

Edit: had to add some goddamn watermarks to them both since apparently people like to use my designs for profit (WHY)

A quick little type 1 (low detail flats carnivoraarts.weebly.com/prici…) ref sheet to show their proper colors and markings. In their original ref sheets, especially Button's, it was a little hard to tell what their markings and colors actually were. So here's a mega simplified version of them

I want to point out that the "defining features" part is probably the most important on this image. These encompass the main elements of their design that make them who they are, in terms of looks. When the three important features are in an image, that's mostly all I'm looking for. I don't mind if other parts of the design are altered, as long as they retain those defining traits.
Ex: Ducky's most defining features are her small build, white neck, and black legs. If she's missing one of those, it's not really ducky anymore. 

Anyway, just made this mostly for clarification (for myself and others)

Here are some links to Ducky's real life counterpart, Luna (whom she's based off of)

Button doesn't really have much of a counterpart, but he's similar in build and appearance to Denali, also from the International Wolf Center:
Here's a video of him (the bigger, lighter colored wolf): youtu.be/hRcuFN6qHcg
