These are all interesting but none of them nails it for me. I'm not quite sure why but a majority of folks have been submitting green (and blue) designs. I understand that green is associated with sustainability but I'd really be interested in seeing some earth tones including subtle uses of orange and purple. I'm not sure what else to say by way of feedback other than none of these feels quite strong enough or memorable enough to me. Thanks very much for submitting. I hope to see some more of your designs.
