Reading the photostory again, I must say the two clowns/hitmen are a nice touch. The way they get in first to catch the customers' attention for their master reminds me of the first Batman movie by Tim Burton (when the Joker meets Vicky Vale).
It's a pity nobody made any compliment on the fish, which I think is great and the key of the story too!
The paint I used for the Joker's hair is Scorpion Green from Citadel, if you need to paint some more fishes!
Best,
