I do agree with this, but I think your bad detail example is not comparable, it is not a build with any form, just a wall, it would be more helpful, I feel if you replaced it with a build that you feel is TOO detailed

I agree, this tends to happen with a lot of the famous map makers, once i try to play cake defense. My computer could not handle all of the red stone, and minecraft crashed. But zombie Apocalypse, the map that hypixel made, it is way to detailed, there are houses that you can't even SEE, unless you get on creative. Not that that's a really bad thing about maps, but just saying.

I wouldn't call your messy detail 'detail', it just a whole bunch of blocks smashed together

I agree.
Too much static/detail can bring the viewer's eyes away from focal points. This essentially just drags the viewer's eye all over the build, keeping it away from where they need to look, and the static can drown out the actual structure of the build.

It depends, I suppose. All builders have different styles, and many very talented builders seem to use the style you're describing as "messy." The image you used for the messy example is a bit confusing, as I know the style the builder was going for, but it wasn't executed well. The wall pattern is incoherent and the ladders on the supports are unnecessary. Something like this build I did myself I would consider the same style of detailing, though perhaps executed better. I sometimes like this style of detailing though I would agree other styles such as lynchyinc's are also great.

In my opinion, there are a few good different styles of detailing. One would be lynchyinc's style shown in your post, which shows detail in the things like the chimneys, windmills, pipes, interior, and the abstract design of the houses themselves. He doesn't use very 'detailed' walls but it doesn't make the build under detailed as he uses these other methods to provide detail. I prefer this style as I believe that these smaller builds with interesting, in depth interiors, houses, and designs make a more enjoyable build than say a large cathedral with extremely detailed walls but empty interior and surrounding.

Maybe you disagree though, I know some people don't like the style I showed above in the picture of my build, but I think it just depends on each builders style and preference. I'd have to agree with lynchyinc's earlier post though, that knowing how to use both these techniques will allow you to make a better build. A nice house with well 'detailed' walls is good, but adding great interior to it, a nice surrounding, and interesting aspects such as those I mentioned above will make it great.

Like I said though, I don't think one person's definition of well detailed is necessarily the correct definition. All builders have different styles and preferences, and no one is right to tell them their style is right or wrong.

I agree :3

I think that minecraft is going through the phase that computer games have gone through. A while back people just played new games because they were more realistic even if the gameplay was utter crap. Now we play games that look like crap but have excellent gameplay, and I think people will realize soon that detail, while nice and pretty, doesn't really affect what's on the inside.
