I, for one am so glad that these more obsessional modellers exist, as I feel their research and knowledge makes them guardians of history, this seemingly insignificant detail (to some) would get lost in this homogenised and dumbed-down world. Their skills will always amaze folks who are engaged in the subject, whatever it may be, military vehicles, 15th century boats, old glass making techniques, whatever.
However, and I write this with a certain amount of trepidation, I have a theory that in making sure that we include every detail that exists on the real thing, can lead to a model being "over detailed". Before you shout "BURN THE HERETIC", let me explain!
Let’s imagine a scenario at a public model-making exhibition. A tank enthusiast looks at a model of a say, King Tiger, they will know what they are looking at, they will expect to see details that they know are there, and will register the fact that they are missing. A viewer who has a more general interest in model making may be unaware of these finer points of detail, and not miss them at all, happy to enjoy the overall effect of the skills of the model maker. A complete stranger to the world of model making will most likely register the model as “a tank” and then fall back on what seems a common, but strong attraction that we all have for miniature things – probably a throwback to their childhood and toys. All of these responses are valid, and, of course, there are many permutations of these main elements of how we look at and perceive things. The same goes for our personal reasons for making these models, so varied and diverse as to be impossible to generalize!
I was happy as a kid to just make the 1/72 aircraft, whack the transfers (as we used to call them) straight onto the plain plastic (at 10, my mum and my purse, precluded me buying loads of oil based paints, which I would have spilled everywhere, and ruined the kit!) and to a 10 year old lad, a little imagination filled in the missing stuff! Which brings me to a significant point…
As an art & design student many years ago, I was introduced to Gestalt theories of visual perception – which help explain how we perceive objects and images before us. The one that has stuck in my consciousness for the last 45 years is “Closure”:
Closure occurs when an object is incomplete or a space is not completely enclosed. If enough of the shape is indicated, people perceive the whole by filling in the missing information.
Impressionist and abstract artists have played on this phenomenon since way before it had been hypothesized, and I believe it is relevant to this discussion, if a little wordy (!). Some of the most visually convincing models, and (especially) figures I’ve seen on these pages have scant detail, but the detail that is there is the vital stuff. So I’m not looking at the fingernails, or eyelashes, but the overall impression of a figure. I will admit, that I would also be very excited about looking at a figure that does have these details; it's just that I am happy to embrace both!
So, let us embrace the whole spectrum – out of the box or every rivet counted, scratch built or snap-together, there are incredible skills demonstrated on this forum from all of these areas, and it keeps us off the streets!
Sorry, I seem to have written an essay, but the initial post re-kindled thoughts I’ve had since returning to this hobby!
I even read there are modeler trying to duplicate the number of rivets with the actual thing. Is it that important? perfectionist? OCD? Never build OOB?
see my aventador built 
but i must admit that i am suffering AMS even i am not an advenced modeller.
