Thanks for participating in this contest. While your designs tell an interesting story, I feel they are too complex. I'm looking for a quick read. Also, the tone in the background would be a challenge to design with down the road.
These (#131, #132) are more simple but I don't think the clamp in the box is very clear or an improvement on the existing similar designs from the original designers.
