I like this design, but I can tell that it's something they came up with only after the production budget was increased and they gave the artists longer deadlines to complete the art, because it's labour intensive (or was before computers).
Personally, I prefer costumes that you can draw in five minutes. Imagine artists at conventions trying to execute some of these designs for fans who have paid for the service, while a long queue of more fans waits to get their commission jobs.
