This is my version of the Krystal model by Mikiel2171. I did several bug fixes and added many new features. It includes both Blender Internal and Cycles versions, though each was developed separately and has its own modifications.
There won't be many updates on this model, which is an older work. I later created a customizable non-fanart character based on it, which I am now maintaining instead. For those interested, it can be found here: http://www.blendswap.com/blends/view/78647
