A personal favorite. This one is so sunny. Parasols are great, but the most joy I'll often find painting near the water.
Kids come and go, of course. I usually paint them either quick in 'groups' of a few, or slower, one by one.
Keeping the perspective believable is the most important part in this, and still make it all fit the canvas.
