I was speaking more of "in theory". Since most of today's resin pieces, are mastered by hand....then today's scratchbuilding skills are obviously of a very high standard. But just because we did not see as *many* examples 20 years ago, does not mean that the skills were not there. I do not believe that there was any "evolutionary" thing at work, that has made today's modelers, any better than a generation ago. Today, I think we have higher expectations, and so modelers who are producing masters, or winning contests, are just pushing themselves harder.
Someone mentioned the "roughness" of many of Shep Paine's earlier pieces. Remember, these were most often built to be *photographed* ... ... not critiqued by the naked eye. I have seen his stuff that was meant for "photos only", and his stuff that was commissioned for the serious collector...and there *is* a difference.
