Diorama ideas

I've got most of the tools to do some resin jewellery but for some unknown reason I've come to a bit of an impasse. I'd love to create some little dioramas of houses and trees, and did some sketches ages ago. I hope I can get round to trying it out some time soon. I've been toying with the idea of buying some trainset figures to set in resin, or alternatively, print images on see-through paper.
