Good advice!
For the time being I'll do a good deed instead and say:

Peter Brueghel used to hide scenes like that in the background of his rural scenes.
Skaters on a frozen river...
Village idiots given to all sorts of mischief...
David, your sky has got exactly that pale eroded late medieval touch!
