#27 is a top pick right now. We are a little concerned that the details in the world map, might not be so clear on printed letterhead or the "TPCH". Could you simplify the world map? For example, like designs #39 & 37.
#39 - like the concept. Can you make the colors stand out more; for example replace the gray with a more vibrant color?
Could you try introducing packaging elements - box, bag, bottle, can - into your concepts? For example, could the cube become an open box?
#38 - would it work to replace the squares with a box, bag, bottle and can. And have a letter on each item.
#62 - can you play with the fonts of the “Toxics in Packaging Clearinghouse”. Could you also try putting all the packaging graphics on top and text below?
