As someone who does DVD covers, I can say it's a good cover. It's a little cliched, nothing terribly original, but you're learning, so that's no surprise. One thing I would suggest is to go to Adobe Studio Exchange and in the actions section there are actions that will create templates for several DVD cover requirements. When designing a DVD cover, don't forget you generally also have to be responsoble for the back cover, the insert and the DVD surface. And those back covers can be a booger to get right, what with mixing text and images and boxes etc. I'd also suggest studying current poster design, especially asian movie posters. Asians are, at the moment, creating the most beautiful and dynamic movie posters in the business, and the posters are generally also the DVD covers.

Talent is God's gift to you. Using it is your gift to God.
