James,
That is a very cute cat. I know what you mean about the playful destructiveness! I love the eyes. The catchlights and stuff in the eyes sets them off. I like the way the white background is exposed. And the poses are great. Even with your shallow DOF you managed to keep the eyes in perfect focus. One thing looks a little off though. Did you end up using a lot of “Fill light” in the Post processing? Something’s is soft and washed out about the dark colored fur.
