Aww, I'm a sucker for dogs. The knife is OOF & has distracting reflections, also the glare in the top l. is distracting. My dogs love peanut butter too!
In my opinion there are a few things wrong with this picture - The Focus of this shot should be the knife as the title of the challenge is silverware. Secondly, the hand is distracting. You also need to put more thought into the background, the reflection on the appliance is also very distracting.
I think the main thing i'm getting at here is that there is no particular point of focus and that there is too much going on in the shot. I like the idea and it could have been effective if you'd put more thought and planning into it.
If I were to attempt a shot like this, I would have the dog sit on a white sheet, have some soft lighting, put the knife in front of him and snap away.
The puppy dog seems to be the subject because the knife is slightly out of focus. It is difficult to get a balanced shot with a camera mounted flash at arms length although your pet appreciates the attempt.
Not sure what to do to help this photo. Maybe a spoon instead of a knife... the knife almost makes it look like the dog is being cut. Natural light would have helped a lot too.
