Dapper Dan - High Key

Here I used the Photoshop brightness/ contrast slider to look at and think about this in a high key way. Where would I lose edges --e.g., where are values the same or similar? Where are the areas of greatest contrast -- where should the sharper edges be? With a high key approach, I would be painting through boundaries, following the path of the darker areas, and simply avoiding the light/ white areas altogether for now. But at this stage, I am simply comparing this high key view to its counterpoint, the low key view.
