My guess is that every artist has a favorite kind of trope or subject matter that they run to as something that is easy and enjoyable. For me, that's my Native ponies.
There's something serene to me in them just...being: an idealistic moment in a make-believe world, where native horses with feather and war paint prance around in early morning light or in overly bright sunsets.
No, as far as I know, I have no Native American blood personally. But my husband claims Cherokee, on both sides in his family and therefore, I hope I have a small claim in loving Native American culture and art.
In fact, let me plug a wonderful little store in my town called "Wings of Eagles", which sells almost primarily Native made art by skilled Native artisans. Here's their site: https://wings-of-eagles.business.site
