Quote: "So, this is a competition to create a scene, not a game, and it cannot use textures, media, external models or sound effects."
You can make a game if you like. It's up to you
Textures, media, models and sound effects can ALL be made using code in DBPro. They also take skill which is what makes this a real challenge. It's not a "Game Making" competition although you could make a game, it's a "Coding" competition.
Quote: "It also seems a little strange to me that the image displayed on the main competition webpage (Destroyed City by damien6160) appears to contain externally designed models, for a competition that doesn't allow it."
That image is just to inspire your imagination, not to represent acceptable content
The idea of holding a coding competition is to inspire you into being creative by placing restrictions on your toolset. A true artist can paint without a set of oil paints and a canvas. A true sculptor can make a sculpture from the dirt on the ground. What can a true coder create with?
Have a try, you might surprise yourself!
Here was my first attempt at a DBPro coding competition from a few years ago now I think, yes Feb 2010:
