Thanks a lot for submitting some great designs, in particular #53 is fantastic. Unfortunately, I was looking for a bit more of a modern looking design. #53 and #54 are very nice and I bet you could find someone else who would be interested in buying that design. I don't think the colors work well in #78, but they work great in the earlier two.
Many noted this concept as one of their favorites when I surveyed a good amount of people about the concepts. I wish I could have given this a medal as I really wanted to medal 4 entries in this contest.
