I don't usually make dioramas, as I'm seriously lacking in the imagination and creativity required. Thought it was time to make an attempt at one, to see if it was viable. In my head, I have a small scene with a priest holding the doorway of his ruined church against hellbeasts. Simple but a nice enough scene.
This is a combination of blue foam, part of a Rubble City set from Fenis Games (https://fenrisgames.com/shop), and Super Sculpey patterned with a roller from Green Stuff World (http://www.greenstuffworld.com/en/). Highly recommend both companies, and Fenris are awesome.
I've never used foam or Super Sculpey before, so this is new territory. Happily, my first attempt didn't suck, so it went straight onto the board! Putting hobby projects in the oven for ten minutes on a medium heat is something of a novelty ...
The tiles in the blue foam are one inch square and created by running a toothpick in straight(ish) lines to make it look like large flagstones.
Priming everything makes such a difference in bringing the scene together. No longer are you looking at multiple textures and materials, but the picture starts to emerge.
Next step is starting to define the differences in colour between the inside of the church, the walls, and the courtyard outside. A lot more colour variety is required, but this is a good start and I'm feeling positive about the direction it's going.
