When I saw this, I didn't see mailboxes. I instantly saw a Steampunk Mad Scientist/Alchemist Locker boxes for his possessions/experiments.
I wanted this to be a little dark and I wanted it to be stylized (hence the extreme lens flare) But the original image I rendered at 100% 200 samples and took like 3 hours to render and then I still get a tremendous amount of fireflies on the back corner. Anyone have any ideas why? I tried covering them as much as I could with out compromising what I wanted to achieve but no luck.
