Looks like the judges didn't like the taste of your chicken at all. Two 4's and a 5 are a sign that something is wrong there. Funny that one gave a 9 for taste, go figure!
I agree about the rib box looking empty.
I really like the brisket presentation, surprised it didn't score better. Maybe a little more even on the slices? They do look a little dry too, but I like the concept.
