My 3 point perspective watercolour camera up and down

I made a watercolor and pen fine liner, 3 point perspective of a water tower, that exists in elephant and Castel, the main idea being that the camera angle is on the ground looking up.  

This one is my self-imagined idea of the same water tower in Elefant and Castel, where I visualised the environment with a drone overhead view looking down in a reverse 3 point perspective, from the first one.
