Very, very happy with the finished product. The design was based off my concept art and exactly what I asked for in the contest description, and all my requested amendments were completed in a day.
I just picked her as the finalist. She had the best design and had submitted about four or five concepts without being asked. I didn't see the point in picking more than one finalist, and we had the final product completed before the competition even ended.
In short, I received much a much cooler cover art design than I was expecting, and I would definitely commission work from her again.
