“No offense Ulrike, but that seems a bit short-sighted. ”
What's short sighted? I feel like you stopped at "Like any other custom, they have to accurately represent the entity they're being applied to". You know, the first sentence.
“The parallel to a station is if I wanted to create a custom image of an electronics store. That's a more generic entity, not a specific model. So why should I have to build all of my custom images based on a picture of Best Buy when there are so many different electronics stores out there? ”
This argument makes sense if I had said that the image has to match 1:1. However, I didn't say that.
“So back to stations. I think our galaxy would be much more interesting if artists could deviate from the stock station images and create more unique designs. ”
You can deviate from the stock station images. For example, as long as a T2 follows the floor plan and the idea of what the station is (a pinwheel station), it's very likely it'll be accepted as a custom. It also has to accurately represent the scale of the entity, as does any other custom. Things like the SY1-4s would obviously have to represent a space dock of some sort, that also follow their floor plans for the most part.
“So stating that a T2 must be a pinwheel station would be a start. Any additional guidelines the art team and others could give would help direct those that want to take on the challenge of making these images. ”
"for example with the trading 2 station, the image used would also need to represent at minimum a pinwheel style station with the same number of major floors (rings)" would be the specifics you need to match for a T2. It's designed to match the floor plan, thus the "same number of major floors". I think that's detail enough on what to aim for when creating your customs for a station. If you want to obscure the rings by having a large sheet or a single tapered ring, there's a good chance that would be accepted for the T2 as well. Smaller rings would very likely be allowable as well. However, completely deviating from the pinwheel design would be denied since it's designed to be a pinwheel.
