I soft of wonder why people's eyes are often more appealed by detailed pieces.
The same thing apply to stories/plot too.
Is this because of something related to mental stability? Something in the sub-consciousness?
It could have something to do with how some people may feel the more detailed a piece is, the more realistic it is. And, then the more realistic it is, the more relate-able it is. I think that if a person can somehow relate to a piece (whether the piece be a depiction of everyday life or a depiction of something that a person is familiar with, such as a religion) they would find it more appealing. But, a more detailed piece isn't always a more relate-able piece. I guess it all depends on how deeply one considers the piece that they're looking at.
For example, this piece by El Greco:
It's pretty detailed. And it's something that some people may find more appealing because it's something they know. A familiarity with something may cause somebody to find a piece more appealing.
Now, you have some less detailed art- Abstract Art. I'd say that that kind of art is partly to invoke some kind of feeling in the person who sees it.
Something like this:
Could give off a certain feeling to somebody which they may find appealing.
All in all, I guess I'm trying to say that a person's appeal for an art can come from different things, such as subject matter or an emotion invoked by the piece, or anything else along those lines really. I don't think it's as black and white as "this piece is more detailed, I find it more appealing".
