Chong made a superb Tutorial in which he makes and animates a Sci Fi Corridor.  He models all the parts needed, (He uses a Boolean approach.)  An important tip is how he keeps the models to 1 meter, and sets the origin points to the lower right of the models so he can tile them later in geometry nodes.

Cables are easy in 2.93 version of blender.

How to make Crystals

Inspiration

If you take a little bit from each tutorial, like the driver part from the first one, the texture the intermediate one, and the volume absorbtion from the last one.  You should have a very good looking crystal.

Idea for the shot:

So, thinking about that shot, need some asteroids, debris, a broken ship, more debris, a salvage ship, an astronaut with a spot light,  and something that tells what happened to the derelict

Elements needed:  Debris, asteroids, broken ship, salvage ship, astronaut

Tutorials used:

Make the ship

Looks great, great colors, composition, and overall anime feel. Inspirational.
