I love the shot! A portrait that leaves me with a lot to digest. The cat is _beautiful_, poised like a silhouette of shadow in a well lit room. Your son's black outfit also contrasts the white couch well, and provides balance for the cat.(posted 8829 days ago)The table , IMHO, isn't all that distracting.
The only real "flaw" I can see in this picture is that _dark_ grey pie-slice in the upper right of the photo. A crop just to the left of it would clean it up. Otherwise, all the other lines work well to my eye.
It's environmental portraiture with a grin - the idea is not to make a masterpiece but to find the masterpiece in life, no? Fine job!
