Hi Christian, yours chosen but must admit that is because I guaranteed the contest and your work was the only work which was not completely amateur like. I actually prefer the design that we had made in house but what to do, you are the winner and you certainly know how to use the software that you use but regretfully the result is not something I can use. Now the question is can you completely change the layout and implement a professional and corporate feel to it... maybe one would have to imagine a brochure from General Motors, Maersk, Microsoft, Apple or any other major corp.
As I do not know much about design etc. I can not really specifically explain what is wrong but it just do not seem to signal what I imagine we are looking for. Is it the strong contrasts or color choice? I do not know but please have a look at it it would be sad I came out of here without anything.
