Criminal Sentence 271: Looking for the Correct Subject

Overheard on Project Runway:

"Looking at the judges’ expressions, they are stone cold."

I feel stone cold about this sentence. Who is looking at the judges' expressions? Not "they," which refers back to the noun "judges." The actual subject--"I"--is missing. Let's add it:

"Looking at the judges’ expressions, I wasn't pleased to see that they were stone cold."

Always make sure you clearly state who is doing what, or else you will be eliminated.
