What is this, I don't even. It is sure as hell not a pony. This was actually kicking around in my head for a few months, and I finally got around to draw it. No idea what is this supposed to be, some kind of a cyborg Shiva? It may be inspired either by Shadowrun or Asura's Wrath. Probably both. Maybe GUNNM: Last Order, too.
I feel that colouring this is a little beyond me right now, so if you are interested in doing it, I'll be happy to let you. And no, I haven't heard of that book before.
Beautiful, very elegant!
