This designer is simply the best out of a large crop that competed for my original cover. Take a look at the portfolio and you'll know what to expect. If I had to list some negatives, I would say that they are a little rigid when it comes to the type of book cover, and there are times when requests have to be repeated before acted upon (I believe due to misunderstanding, not at all lack of cooperation).
Overall I am very happy with my covers. They are worth every penny.
