In an email, Kevin explained the concept and I thought it was great fun. I did the two sketches on the left for him to review. While the far left sketch has a dramatic angle, it does take away from showing Phantom Lady's curves and short-shorts legs. We both decided a variation of the straight on approach (the middle sketch) mixed with more body expression would be better. The sketch on the right is closer to what the final line art will look like. Which I will share tomorrow.
All the sketches were done in my sketchbook using Col-Erase pencils and graphite pencils.
