Stamp Design: Creative process: Photoshop iterations, continued

I began experimenting with balancing the composition with more magenta. I used the hand-rendered traffic light circles superimposed on a Photoshop 'shape' of a contrasting color. I then utilized drop shadows to emphasize informational elements, and introduced a longer tagline at the bottom of the stamp. This creates an L-shaped border along this side of the design. Along the way I learned what 'use global light' means while applying drop shadows, particularly when attempting to orient them in different directions.
