Here's a better version of my 3d illustration. Yesterday I had to deliver whatever I had ready by deadline time and unfortunately I didn't have all the time I needed to finish it in the way I would have liked to. Not even to check it through actually, all I could do was save it and send it.
Still, I'm quite happy with what I've done and of what I learned doing it.
I will eventually render it in another program other then Zbrush with a proper set of lights and all that, for now here's the same of yesterday with some extra work in Photoshop to bring it towards what I had in mind.
