It would be great to have a feedback on my submission.

Can you open up the contest again? I just finished my design.

I did end up extending it.

I only saw the post with less than an hour left to go and tried to get it done. I haven't been following since it was posted. Hopefully you have a design that works for you. If nothing else, now I have a great base design I can use for my own work, obviously with some modifications.
