Those are interesting, Paul. Love the tiki hut (and now want to make one,) and the one using artillery fern as a tree. Brilliant!! Like a real garden, there's no right or wrong for minis, but I do love when there's tiny, proportionate foliage used in a mini.
My newest mini is now a "sinkhole" garden, I guess I'll say it's a Florida scene. A squirrel or chippy has dug 2 deep holes in it. Looks better than if I'd tried to do that on purpose. Those little furry creatures can't resist joining in on any kind of gardening. (And that's a feature you just can't buy.) LMAO!
