Eomer

Here's a minifigure habitat I made towards the end of my series of small builds. If you look at the base layer of yellow you can see I was running out of bricks and was substituting with plates.

Éomer of Rohan (a Lord of the Rings minifigure) stands guard at a gate in his palisade. Behind him you can see some experimenting with small-scale landscaping, with green slopes, curves and plates layered to atttempt some sense of an uneven hillside.

The large arches on either side let a lot of light into the scene, even when stacked in layers with other vignettes.

Not everyone has the time (or the bricks) for full-table-size dioramas, but sometimes smaller builds are a good challenge as well!

"Habitat vignettes" are a very popular method (just do a Google image search) of making little displays to showcase individual minifigures. Every year when LEGO releases a set of Collectible Minifigures, a lot of people around the world find cool and creative ways to display them in a small "room" themed to the figure.

With a set size (12x12 studs in area, 8 bricks in total height), it is easy to make one or more and assemble them together into a "wall" of little rooms. This is what we did in my club last year, with multiple vignettes on a single table as part of a group display.

My first was a lion cage to show off the Zookeeper minifigure (Series 5). It was fun trying to figure out ways of securing the vegetation at different angles to give a more "overgrown" look to the background.
