Beautiful dog (I wondered if we'd see any yellow labs). I wish you had got a bit more distance between the subject and the backdrop, the wrinkled fabric really mars the photo. Otherwise very well done.
What a great looking dog. The wrinkled background, however, is a bit distracting. Either the wrinkles should have been ironed out, or intentionally included. As it stands, neither looks like applies. Just a thought. Worth trying again, though. Happy shooting.
