I decided to be creative and changed the sentence order a bit Just didn't know where to put the "prize winner", didn't have enough details for that.
I am an professional graphics designer with ten years of experience in this industry. My creative ideas and vision supported by knowledge, proved to be extremely successful, during my working as a freelancer. I believe, that your organization will benefit from the value I can bring, and I will be grateful if you considered my candidate.
Good luck with the job :)
