I like how bold your design is. I also like the keyhole effect within the "magnifying glass" or the key handle. I really do like the key concept, but on Entry 15 don't like how the four narrow lines come down from the end of the key. I would like that better if the key end simply the bolder grey/or black. I ranked entry 10 higher because of the color scheme.
I have updated my contest brief and added a request for a new color palate. Please check that out.
Ahhhh. I've just notice that you've added Entry 19 - really cool. I like that one but would put the key end on the point at the right.
I'll move that one up in ranking.
Thanks for your creativity. I appreciate your contributions.
