Yes, you can - and will - judge a book by its cover. It is well established that cover art is the very first thing that will draw a reader in. For this reason, it can be argued that the cover artist is every bit as important as the author in the success of a book. Below is an interview with Krystle Wright of Deviant Art...
Tell us a little bit about yourself. How long have you been an artist? What inspires your work?
Art was never a phase that I would grow out of. My father wanted me to be a Nurse but Art always brought such joy to my life. The kind of joy that I couldn't forget. I stumbled into Cover Art Design because my husband needed a great cover for his book. We searched & searched then finally I said "Let me show you what I can do!". I'm inspired by the amazing stories created by talented, creative & highly intelligent Authors. These stories made up of extraordinary moments, discoveries, adventures & characters help me bring light to a cover where it is needed.
What book genres do you prefer to create cover art for?
I can create Art for all genres however Fantasy is really fun because you're creating another world.
What other artists would you compare your work to?
Being unique is what true artisans strive for. I've been seeing many book covers that book bloggers are featuring & almost all of them look incredibly similar (Model showing emotion & light, bright, airy color schemes). Standing out from the crowd is not always wanted unless you achieve this with overwhelming beauty.
