Thanks man 
This was done in ZBrush, but I use ZBrush only to create models (it's a 3D Sculpting software). So apart from unfinished parts, the actual render (in the coliseum with all the things) is yet to be made. After the render, slight images adjustments are made in Photoshop (lightning, ambiance, etc...), and if you want you can check how a final render looks like at my gallery (http://elementscommunity.org/forum/index.php/topic,18400.0.html) (see robot, 
Temple, or Entangled Roots art in the last 2 spoilers)
Also ZBlader, is this guy ok for you?
A gladiator type charecter also fits the card's theme, so it's perfectly fine.
