My first building made for wh40k. Also my first building ever. It has LED lights build in to make the mood :) I am a beginer so comments and tips are welcome!
While it's ok to use things like nuts and bolts, there is a rule I follow when doing those things: It needs to look like what it's supposed to be, not what it is. That is to say, they look like bolts, not power coils. They need to be modified, converted or disguised to not look like what they are, be it bolts, soup cans, d-cell batteries or whatever else you scrounge.
That being said, I like the lighting.
