How to get these effects?

How would I go about making a sig like this?

 

Hue layers.
Looks like some kind of grunge brushing or something set on overlay.

and just use hue layers to color the two halves.

 

That's how to do that icey effect?

 

ohhh

They LOOK like some kind of fractal/grunge brush. try deviantart for some good ones.

 

I tried searching for scratch brushes and brushing the sides, and to say I did bad is an under statement.

 

It's an older form of signature making. Just brush the whole signature with alternating fractual brushes and grunge brushes, and erase on top of the render. Set the layers to overlay or soft light.

Turning it to Overlay or Soft Light totally got rid of the brushing. This is what I got after brushing and erasing.
