I like vignettes because they’re like miniature dioramas. Regular-sized dioramas are equally awesome, especially when they involve a mecha. I’m just noticing W. Roger Stroud’s work for the first time, mainly due to a very cool diorama he recently posted to Brickshelf:
Roger’s diorama also includes several excellent support and diagnostic vehicles, so check out the gallery on Brickshelf or his page on MOCpages.
