Yeah, still working on photographing. I'm working in a dim basement with not a lot of time to set things up. But I do have another one of these...your diorama idea is a cool one. I like all the Reaper versions of these classic critters. I'm actually working on a series that shows the evolution of classic minis--mind flayers, umber hulks, rust monsters, and whatnot. If anyone here has any ideas let me know!
Cool old mini. It would be fun to make a vignette with the baby Reaper Illithid and this one together. I can't really make out the colors with the yellowish cast to the image, but you should be able to fix either with your camera settings or an Image editoer like Photoshop or GIMP.
