Hello!

Here are some reference images I wanted to share with you concerning your current assignments. Although these images don't necessarily adhere to your assignment's formal constraints, I feel they each represent interesting methods of how to visually convey multiple layers of information. Notice their sparse and selective use of color, gradient/fading "wash" techniques, varying line types and weights, careful use of imagery, intricate but light density, and overall subtle nature. All qualities your current drawings should carefully contain. Be delicate but deliberate, soft but firm. Efficient! Good luck!
