Angelina Jolie's Digital Portrait painting. {Line art Phase}

Here's the "process" I go for line art and sketching, plus the painting. =)

I choose out my colors and do the face shape. 

I lower the opacity of the layer to about 55%

I draw over it again =)

I lower the opacity again (I forget how many layers this is now. But I end up merging all the sketch layers together as I continue drawing.)

Then with the pen tool I create the line art.
