The context also seem to be wrong on closer examination. The 49ers are on offense from their own 20 yard line. The 49ers own crowd seems to be visually overly enthusiastic when they need to be quiet on offense. Would like to see more contextual awareness. But then again, I've seen and heard 49ers' fan get rowdy when they're suppose to be quiet.
As far as the image is concerned, I would like to see the sidelines filled up with more stuff. If that means removing some characters from the crowds, it would be appreciative.
