I was an attempt to shade using a different color palette than the one the picture had originally. It isnt bad, but it looks strange. I may use it in a future, but I don't think I'll use it in my colored comics yet until I perfect it.
Also another detail of this pic is that the "borders" were drawn after the pic was "complete". It gives a very interesting effect to the picture, but it only works for sketchy stuff like this.
