My standard  is simply to build as cleanly and accurate as I can .

meaning no gaps , filled seams,good fit, no exposed glue..ect..

I think of  it as a core requirement

I have a long way to go before I am at the level of ,lots of aftermarket ,photo-etch,heavy scratchbuilding.weathering

I figure If I concentrate on the basics  than those advances will come over time.

No amount of  bells and whistles matters much if the end result is sub par

I have heard of clean precise box stock builds taking trophys over highly aftermarket builds.

so for me it's simple,,nail down the basics, and gradually go from there
