So i will know join the discussion about the logos. I "borrowed" it, like someone said, from the internet and I have no problem to use it for my banner designs. The organizers of the contest challenge us to use the logos but when they don't provide the logos, we have to borrow them. I assume that the competition is discussed with the partners, so that we have the permission to use theire logos for the contest. But i don't know whether we can change them ( for example the color) or not.
For myself I rather have the problem, with using foreign pictures. Because I know how difficult it is with the licences. Sometimes you can use it, then you can just use it, when you name the owner and the source where you found the picture. This is not a criticism, just a note and a piece of advice for those who did not know this.
I hope I didn't discouraged anyone, i really llike the other designs and hope to see more variants.
