Nice shot, and a good magazine cover, with a vertical format and space at the top that could carry type without spoiling the picture. Could use a bit more DOF to get the paws in focus.
Lovely cat, almost a great picture but let down by some overexposure on the fur, and an annoying green distraction in the background. The background in general seems random and takes away from the possible impact of this shot.
Beautiful composition! Actually its perfect! DOF is excellent... a bit bright on the white fur though but that must be tough to avoid. Well done! Hope you do well!
