In the past of have done models of both the Roman Colosseum and Parthenon. I did them as I imagined they would have looked in their heyday.
I occurred to me however that it would be even a bigger challenge to create them as they appear today. It involved spending many hours of research, drawing plans, hunting down textures and then finally executing the models.
... and it hasn't finished yet.
I eventually want to go on to recreate the entire acropolis and the surrounding areas of the colosseum.
It will take a few years to complete everything I want to do ... so keep watching this space.
