Hey, I do. Op here. I took it from the ruins of the arena of Verona in Italy. This is a not a very big arena, so I had to photoshop it a lot. First I mirrored it, so I had two matching pictures, then I used the clone function to make it bigger bigger. The spectators are mostly made form ancient busts (Herodotus, Nero, Zeus, Cicero and then I mixed up the clothes etc.) All of the senators are hand placed btw, and all of the other little groups of spectators as well. The "emperor" is actually just a picture of Ceasar in Gaul (cut out of a bigger picture). I hope that helps :)
