I just don't understand why it's so hard to make the mini represent the art we love so dearly. Perhaps I just don't understand because I'm not a sculptor & do NOT have the ability to do that kind of work...but I just don't get why there are so many that are just...off.
You've hit the biggest part of it already. Try to imagine a task where you're expected to:
A) copy something exactly that can't be copied exactly.
B) re-create it exactly when viewed from multiple angles while only having one angle to work from.
C) sometimes use multiple sources that conflict - again, matching them exactly.
D) not copy it exactly where its "bad" in someone else's opinion.
E) Make it in as few pieces as possible while making it as flexible as possible.
F) not make it too stiff, whatever that means.
G) not make it too dynamic, whatever that means.
H) make it to two different scales at the same time to please everyone.
I) include extras to please more people.
J) absolutely don't compromise anything to please more people.
K) do it all down to the millimeter.
L) have it molded and cast, which can mess with proportions even if you've navigated all the previous requirements well.
Sounds easy, right?
