Turn object to Ice - part 1

Find an object you would like to turn to Ice. I'm using a skull in this example.

First select the object, I used the magic wand tool for this because the background is one color. now copy it, Ctrl + J ~ Now desaturate the layer; Shift + Ctrl + U ~

Now go to layers, layer blending mode arrow and select the exclusion mode.

Now copy the exclusion layer and set mode to screen 50%

Now make a layer of light blue and set it to overlay 50%
