Very pretty snakes! I think that last pic is my favorite. The blurred out driveway and perspective make the snake pop. I would suggest you find a more contrasty background for your snakes. With the gravel it doesn't make their colors pop and the texture of the gravel being in focus doesn't keep my eye on the snake. I'm into photography so I hope you don't mind my suggestion. Just trying to help.
What about on tile pieces, wood deck, grass, hanging out of decorative bowls, etc.
I love the funky patters on your YB and pastel, especially that pastel. So cool. Looks like someone was playing with watercolor when designing his pattern.
