Okay, here's the finished version. I think Mike did a phenomenonal job on it. He does so many things well-- the soft blue on the planet and the glowing ring around the it, it looks cool without drawing too much attention from the main subject. He put a rimlight on both characters and that just helps give them that extra touch of roundness to their form. And the little sparkle from the blade-- a nice touch. These are just a few of the little things that Mike does to make a piece "pop," I can go on about it but I'd be typing all day :)
You can view the completed version with the logo and type on it over at the Dark Horse site. They've cropped it quite a bit and (to my surprise) actually have Rholan's blade coming in front of the logo-- that was something I thought they'd never do.
