But you already did...? Well the style has been altered, along with that technique and methods have changed too (e.g. characters use normal maps). I believe, the picture you provided is back from early/late 2009, and today is 2015, soon 2016.
I don't think the method, they are going for, is using none of the techniques showed above.
Even rim lightning I think they took it off totally or its there, but heavily altered to match the style. I don't know need to check the latest video to see. I might be mistaken, but anyway on top of that, there was a video somewhere so you can see what kind of approach they are heading forwards.
