I have seen on the winner about screen metadata that it is marked as "proprietary". I can see no citation about free content licensing on its page at devianART and I also notice that there was no requirement for free content licensing on the contest rules.

This could lead to problems on packaging for debian and other gnu/linux distributions that have strict rules about licensing.
I think that we should add this requirement on the next contest. We should also verify which license does needcoffee intend to use on his work (same is true for the #2) and update the SVG metadata.
