ok, I\'m going to go at the question from a different angle. We can go on about what techniques are prefered or not, etc...
However the ultimate goal of miniature painting is to create a convincing illusion of reality (even if a fantastic reality) at this scale which is captivating, interesting and hopefully original. So I would say the perfect miniature would do this perfectly.
Creating the illusion of reality requires a number of factors
1) No mistakes at all, nothing to break the illusion
2) Textures which acturately mimic reality. This means perfect blending on some surfaces, or gritty look on others which might require it for the illusion you\'re creating
3) Completely accurate use of light. This is a tough one, and most \"advanced techniques\" seem to revolve around it. But accurate the use of light, reflections, highlights and shading are vital in creating an illusion of reality.
4) No fear of freehand, but also no overuse either. It needs to be approprate to the illusion you are creating.
Ok, now that we have created an illusion of reality we\'re only half done, and arguably the easy half. Now to this concept you must breathe life, interest, captivation all with a twist of originality.
Just as the practice of completely lifelike canvas paintings went out of style 100+ years ago, I feel miniature painting must take that step beyond purely striving for creating illusions of lifelike reality. To really captivate your viewer there must be a sense of style and originality that they might not have seen before. This is built in addition to/on top of the illusion you\'ve created. Reality with style so to speak.
Now, once you\'ve mastered this...you might have something
ok, well my ramble is through, I hope I managed to make a little sense, although I won\'t bet on it...
