I came across this design on 99desings (Logo design contest | Rain 6 needs a new logo | Entries | 99designs). As I was looking through the entries I found several that would fit my logo PERFECTLY. Would it be copyright infringement on Rain 6's chosen design if I were to contact and purchase one of the losing designers designs? While I wont be using the final design chosen I am worried that since they are all so similar to the final chosen design that I might run into issues. Thoughts?
