Voted earlier, just coming back to comment. I like this idea! The lighting looks a little harsh on the dog and I wish the table cloth was flat. I do like how the dog has that "guilty kid" look - he knows that he can't get out of it, but he's going to keep arguing until there are no more options left.
I appreciate the work you put in to make the sign and set up the props etc but the pic doesn't really have anything in there to hold my attention. I usually comment and try and think of ways to make it better but i'm not sure I can here... I just don't have a clue.
