8,9,10, all with the closer person badly out of focus, look awful.
Back to #1 which mwcfarms mentioned the lamp shade growng out of his head; to me, the worse issue in that photo is the way the light hits the dog first, making the dog the brightest object and most-noticeable, then her, and then leaving the man's body,arm, and black sweater as a black,black, detail-less "hole". Also, the reflection from the flash off of the background's varnished wood "whatever" is very distracting to the eye. This shot suffers from a fundamental lighting mistake...the light is coming in from the "wrong side" so to speak, and is badly aimed. Probably due to using a speedlight, and being unable to actually see that the man's body is not lighted, but the dog is. If the light had been brought into the scene from the left hand side, the two lighting issues would have been eliminated.
I was getting ready to do a milk carton illustration asking who had seen you and to see if somebody would come forward top claim the $25 reward...
