Unclothed:
A quick note: Per the usual, in the Rainbow Pool image, the Royalgirl has the Royalboy's eyes. The versions above have the right eyes.
Royalboy: I'm really fond of the tropical clothing and overall design. The collar around the neck seems more detailed though, so it sticks out a bit. As for the base color, it's odd, but decent. I think if it was more of a green than a teal it might have blended better. Also, oddly enough, the cornea of the eyes actually have a brown tint to them (so do the Royalgirl's, actually), similar to how the underbelly is also a light brown instead of white.
Royalgirl: I think I like this one a bit better than the Royalboy, but that's personal preference. My only issue with the clothes is that the sandals cut off the tips of the toes/claws. As for the base color, I really love it. It reminds me of some sort of tropical fruit. Yum!
Tl;dr - Two very nice Royal pets, even if the brown eyes are a bit odd.
