The effects on the signature are really good... I love it but perhaps sharpen it more.
Seems a bit too blurry and the Tiger looks like it haves a Gaussin Blur to it but when it gets closer to the render it gets "Less" blurry, perhaps you should do it the other way around but it seems to fit so KIU
you should really make a tut on how you do this.
or you got secrets you would want to share ;]
