I woke up with the nedd of making a skin, at first I tought about a nova with marble and black parts, but didn't work out, after that I tried a more straight and futuristic pattern, as you can see the black idea remained.
I had 2 options, blue or red, the blue one gave me more an idea of calm, order, while the red one was cooler and mrore chaotic.
So I went for the red, if you'd like to see the blue one please write a comment and I'll include some screenshots.
