I don't mind people saying things like (assuming I'm building a model to be accurate representation of the real thing and not syfy or futuristic ) the engine is the wrong colour, or as someone has suggested the wiring loom should be covered in some sort of black canvas material, things which are constructive, but not in the way we decided to portray a model, I hardly ever build like a model just came out of the factory, I like adding ageing, I think it makes a model more interesting, but that's just my preference, I wouldn't tell someone who built a pristine perfect car with a perfect paint job and not a speck of dust, they had built the model wrong or been lazy, I've seen some amazing examples of both types, and thats what makes looking at other people's models so interesting, if we all built as the box artwork every model would look exactly the same (apart from a colour change that is) so I will continue doing them "my way" and take advice on better ways of doing things or making things more accurate (skills allowing) so thanks mate glad you agree.
