Here's another from the Eel Pie Island series. It's of some old machinery, looking hopelessly neglected, but in fact still used. Not sure anyone knows what's in the red drum.

I was commissioned to draw a series of pictures of the island. It's a curious place, oddly out of step with the 21st century, and full of interest.  Here's a view of the boatyard, one of the few still operating on the Thames.
