Hi,

For now I'll submit a temporary design to make sure I'm on the right track. If possible just give feedback on the design so I can refine it and submit my final design for rating.

Thanks

Hi, Ben
please, don't close the contest beforehand

I am not planning to. The whole point of this is to see an array of designs and to have options, rest assured, I'll be waiting to see all the submissions before making any decisions.
