Sketch of Minas Tirith

Because I have so far drawn people from Gondor with a Greco-Roman influence I picture their architecture to follow similar inspiration. I see Minas Tirith as a version of Rome if it had been built on the side of a mountain. So lots of columns, tympana, huges domes and decorative swirly bits everywhere. Here is a sketch of the city seen from the front, with the natural cliff in the middle. I picture the palace on the top level to be close in size to St. Peter's Church in the Vatican, so this is a monstrously huge structure.
