I am currently starting project "Taj Mahal". I will be posting pics of my progress here. It will be a mega structure and will take some time. Eventually if you want the map sent to ya just pm me
The base is the most important to every Project. Make sure you check the real proportions of the original and Keep the scale all along. In your last Picture I get the Impression of a rectangle, whereas the floorplan of the Taj Mahal is a square.
