Setting the scene at sunset
The image could benefit from more contrast and darker colours, so I create another Multiply layer to add some warmer shadows. I also use the erased parts of my shadow layer as a selection to fill in a dark brown colour on Linear Dodge (Add). That gives it a sunset feeling. I add a gradient from bottom to the top, which makes the dress darker and increases focus on her hair.
Merging the layers
Once I’m happy with my colours I merge my shadow and light adjustments, plus the outlines, with the three layers from earlier. Now the rendering starts! Since my lighting scheme is already in place, all I need to do is to tighten up and add more detail. I also introduce more painterly brushstrokes, because I want to make it look like an actual painting.
