Its Van Kleiss and his fabulous hair! It does look different! Not too much, but the shadows are harsher, it feels more gritty than your other method, and not just because there is a lot of grit in the image. It's super nice, awesome work!
You think there is a difference? I am glad it is noticeable! QuQ I am still trying to decide if I like it better then my usual stuff, if it looks better and what not, but I did enjoy this method of shading.
