So I made these levels one day a while back and I saved them in gimp and called it 'Purple Roses' and today I was/am making a bunch of Rose McGowan icons because I had made so many Rose McGowan icon bases a couple days ago and wanted to make use of the bases. Before using these steps I smoothed Rose's face out with the blur tool, you don't have to though unless you want to.
Step 1: For the first step duplicate your base and then go to Colors > Desaturate and set it to Burn 21% Step 2: Next go to Layer > New from Visible then go to Colors > Levels and put these values in:
Step 3: For the Last Step go to Layer > New from Visible and then go to Colors > Hue/Saturation and on the Master put Saturation 20
