I created this little lovely a couple years ago and I ran across the pic today and decided to post it. She still is one of my favorite alien designs I've done so far.
She is a Kre'ell. Her people have only recently achieved space travel due to outside influence (they're highly intelligent, they just never felt the need to create technology themselves, any tech they have was given to them or stolen from other races). They're telepathic and use their delicate antenna to touch things, like the controls of space craft. Not many races trust her people, as they are known to be violent and aggressive creatures, most other aliens still consider them animals. Their armor is generally dark in color, while their luminescent spots can come in a variety of bright colors. These spots can be flashed to communicate to other Kre'el.

The Kre'el belong to me.
