How to use DMX?

On my show, I used DMX at 2:54 (2 minutes, 54 seconds).

In the case of the sailing ships directly on the hull, in the case of the building without any special positions directly in front of it. I have achieved my goal of highlighting the objects in color, but I would still be interested in what could have been done better or differently? I’m looking forward to your suggestions, Bernd
@Lukas: Since I find the interplay of fireworks, music and light fascinating, I would be happy if you could buy the DMX function separately without owning Fwsim Pro.
