Tales from the Middle Kingdom

When I was little there was an anti-litter campaign in Hong Kong and they had these posters showing a pair of angry eyes, I guess to stare at people and shame them into not littering. I was reminded of those eyes as I drew the last panel. I guess it was a pretty effective campaign if I still remember it all these years later. I tried finding a picture of those original eyes on the internet, but no luck so far.
