When I was in the local thrift store a few weeks ago I chanced on a cheap Christmas decoration in the form of a plastic light up church. It had a single mid-sized bulb that illuminated the interior through some front doors that were slightly ajar, and some hideously colored windows.
I thought I took a WIP or preliminary photo but I don't seem to have one. Getting it ready for 'grimdarking' took a little work. I had to remove the doors (breaking them in the process, no idea what kind of glue they used), I attempted to pry off the acetate windows, and I had to block up a large gap in the back where the cord for the light came in.
added some 40K bits to the outside, some candles, and a picture to the interior. The Aquila and
picture frame are 3D printed. The image of the Emperor I found on the internet- that is a print out. I have not been able to discover who the original artist is [EDIT: looks like the artist is "NeilDY". They had a DeviantArt page at some point, now unavailable]
I also painted up a Reaper 'Bones' crone miniature that seemed like a good down-and-out pilgrim.
I couldn't resist a quick double exposure with a little Photoshop (mainly just selective erasing a very dark image that was on top of correctly exposed one).
