I summed up few things usually associated with this creature: at first she was just a common monster but her myth has changed with times, later she was shown as a beautiful, yet dangerous creature, hunted by heroes but also loved by gods (Poseidon), with wings and serpent hair which she got after Athena turned her into a monster, being jealous of her beauty beauty (weird for a goddess of wisdom, but hey; she failed with the apple as well). So to show her in a different era I decided to put her in space opera setting and give her holographic wings. It was a nice exercise - something new for me, that I always liked, but never painted. I also didn't use any references at all, wanted to see how far I can go without it. Done in Photoshop and SketchUp (simple 3D model of the city in the background, which I later repainted).
I might make a tutorial out of it, when I have time, as I saved most wip shots. Or just a usual gif ;)
