Trackplan looks good to me, and a bit late to change now, but a bit of disguise might do the job. Maybe it is a bit one-sided with the container and most of the track at one end. A small shack or object in the big area where the shrub seems to be would balance things more. Or a bit of fence near the headshunt - prop a bit of cardboard in different places and see how it looks. I like Cookie's fence here http://forum.gn15.info/viewtopic.php?t=2355
I don't think of small industrial railways as having trackplans - the rails are narrow and the track is inset into dirty grey stuff or else buried in dirt and weeds, so the track sort of merges into the background.
I like how you called your layout a folly; reminds us that layouts should be fun.
Incidentally, you can break up lumps like limestone chips by putting them on a big area of concrete, bashing with a hammer, sweeping up. I did this on my drive. I noticed that the drive naturally had a coating of fine material - sand, dust, grit, bits of unknown matter - that was good for representing 'ground' on my layout.
