Thanks for the comments, everyone!
@War: Yes, it was the subdivision. I had rendered one version and thought it needed a higher subdivision level, and I knew that would really increase rendertimes, so I just increased all the subdivision levels (rendered this overnight) and hoped that it would be done by morning!
@simhar: Thanks, I’ll see what I can do about a .blend. It probably won’t be posted until tomorrow, though.
@jackblack: Thanks! The back wall mesh is actually completely flat, and the ground is fairly smooth as well, so there’s a lot of displacement in this image.
@Jacco: I’m not exactly sure what you mean about the 24 verts, but I’m glad you think it’s not just terribly done. I agree with you, though, it is rather simple in composition and content.
@Peasley: Thanks! I’m glad you like it.
@The M.h.p.e.: Yeah, I had to depend a lot on displacement because I’m too lazy to model the ground. You have a good point about the contrast, also! I may go back and do a tiny update there…
I also wanted to make an image that people could really think about and “relate” to, so I’m glad you thought that. Thanks for posting.
@Cyborg Dragon: Thanks! I thought about putting a lot of different objects in that were related to the Crucifixion, but I was kind of afraid it wouldn’t work out well, so I just left it simple.
