Princess Emerald is really full of character. I love the steampunk feel she has. I chose a color scheme based on her namesake. I'm planning on doing this with the other princesses as they come out.

This Princess Ruby is a re-sculpt. To be fair, I was quite fond of the original sculpt for Princess Ruby, but I recognize that as the style of Super Dungeon Explore evolved, she was a little left behind (Ruby would be far shorter than her sister princesses at least).
And I was quite happy to paint her up again. As with Emerald, my color scheme was based on her namesake:

So we're waiting on the Super Dungeon Arcade box to come out so that I can have a go with Princess Amethyst next.
