Illustration depicting a certain Amazonian Warrior Goddess in a state of bliss after a night with a certain Kryptonian.
I used the following photo of fitness and glamour model, Denise Milani, as the starting point.
Using the pen tool, I started with large, flat color shapes to create my base layers and clipping paths.
As you can see from the work-in-progress animation below, I built up the shadows, mid-tones, and highlights using different blend modes for each.
When it was complete in Illustrator, I imported it into Photoshop and overlaid a grungy, paper texture on top to give it a warm, antique-y feel.
