Hi Kertis! As @Wyvern said, I did everything in just one FCW file, using different sheets to "isolate" the two drawings (towers and landscape) and thus make the work easier.

Apart from that, at the beginning of the composition of the design of the towers... I used a drawing from below as a reference - in order to facilitate the work - which I also use in several other styles (overland, isometric, caves etc) that I know as Trace.

The trace greatly facilitates the initial work.

This video is an excellent tutorial on how to use it:
