I don't see anything remiss here, you obviously had a tidy up before the piccy but even so its quite tidy by veg/bio standards.I find vacating a property and moving into a new one is more "energy efficient" than me cleaning my old one!
I have to ask...why have you (had you) got so many used filters draining in a bucket. Do you not throw anything away?Good luck in keeping your new shed clean. I must admit that when I rebuilt mine 18months ago with a bunded area and a vinyl floor, keeping it clean and tidy is now second nature.
To give you all an idea of why Julian has posted this this is a photo of what my shed looks like after the reactor was removed.
