Hey BloodyArrows; we can't modify the body mesh in any way; the only thing we can do is sculpt and apply different textures on it; so sadly enough something like that is not possible; unless you flatten it out on the existing model, wich will probably result in something.. well, flat.

HI I too agrea...Stenchfury you can use bump maps with density and play with textures to give that Dragon tail look also to lift more scale skin on this skin in which you'd like to release...your using zbrush right? Being a zbrusher myself I know there is so much tutorials on how to do it...I great idea for your skin I'm just finding the helmet alittle hard to make out the dragon face in your pictures.
