Thumbs up! (You get to live!) Excellent rendition of the Flavian Amphitheater, you covered all the important bits like the arches, awnings and most importantly, combat. The microfig population is an excellent touch, really brings this model to life.
Looking at the thumbnail, it looks like a photo of the real thing. Clicking on the thumbnail reveals it's obvious LEGOness. I like that. A very realistic build that is obviously LEGO. The use of the LEgO games figs is genius in my mind.
Nice work! And nice microfig collection! Are they all yours?
Some thoughts on improvement:
All thoose tan pieces gives it almost too much conformity. The yellow fence pieces provides some nice contrast from all the tan. Perhaps you could use some light grey pieces to break off from all the tan. The seats could be a candidate for some light grey, maybe they are made of some other kind of stone.
Perhaps you would want to tile the floor under the valves on the outside of the colloseum? (parts doesn't seem to be a limitaion for you...)
Again. Nice work!
Goodness gracious, what a fantastic piece of work. Great work with the circular construction and I love all the microfigs in there. The details throughout are astounding. Just a couple chariots and it's complete;)
