Need alien inspiration

This is D'Ni, I see her as an intelligent galactic traveler, explorer, and ambassador between worlds so I gave her a lot of clean looks and official styles.

These are some extra outfits I made for her.

Here is D'Ni's travel companion, Rom-ULAS, the robotic feline. I wanted him to look like he was lit up underneath the robotic plates, so I just traced the lines with a light blue. I'm not entirely pleased with the effect, I think I should have used a lighter blue-white color. Oh well. I still love him.

This Alien, Qhawa, I made to join a group for a Selvadoradan adventure. In her human disguise (not pictured) she looks like a beautiful local native, and her part in my story was to be the exotic pathfinder and lore teller. But secretly she's a guardian for the ancient Alien temple, there to spy on anyone who seeks to uncover the mysteries and steal the treasures and magical items that belong to her people, and sabotage their mission. I chose the cat-eared hair for her because I thought it was amusing to think that one of the ancient secrets was that cats came from the Aliens too, from somewhere out in the great Beyond, and are superior beings. It's an ongoing theme in my games. :D So I chose styles that reflected the flora of the area for camouflage, plus some that hint at the strangeness of being from a completely different planet.

Finally, this is Ti'Ana, a young colonist, sent to mingle into Sim society and observe. She's still learning how to dress in order to blend, and some of her styles come from Alien materials so they have a natural phosphorescence. I chose a "bug green" color scheme for her because I thought it was a good way to portray that. Plus, I do like to have Alien clothes match their hair and skin sometimes. :)
