If they aren't kept abstract, then the whole point of the exercise will be missed. And if you're an S of any kind, the whole point will probably be missed anyway.
Maybe I am missing the point, but I thought the point of a "guide" was to help people understand things. And if they're overly abstract, then their meaning is unclear to the majority of people. Guides are meant to be clear. So if it is abstract, it might as well be easy to read.
And if you meant it as an intellectual exercise to argue over which pictures are more Ne or Ni, then you ought to rename it, because that's confusing people and not guiding them. I will guarantee you that if this thread is like the other one, people won't come to it to find an easy-to-understand pictorial guide.
I like the idea of an abstract pictorial guide. But sometimes metaphors are simple, and sometimes they are only understood by the person choosing them. Consider the number of Intuitives who didn't "get" the pictures in your last thread. They required too much explanation.
Again, maybe I'm missing the point. Maybe you want them to be abstract enough that they aren't helpful to everyone. But from a Te perspective based on efficiency, I'm just saying that there could be clearer pictures.*
*Although to reiterate, I did like the two that I pointed out quite a lot, and they were very abstract, but still helpful, which is the point. It's not a pictorial guide if it requires a paragraph of accompanying text.
