Excellent model LordGood ! On my point of view, there's only one thing to change in this design : the shape of the repetitive ornament/arch. For now your version of this typical Mauryan arch is like a spade. If you look at the references and at the actual Mauryan buildings included in the game, you'll see that it's not a spade shape but a half-circle, more or less. Spade-shaped like for now on your model, it looks a bit too "Elven". For the rest of the model, I have to say that you reproduced the original brillantly... And don't worry for the count of polygons, it doesn't look low-poly at all !
