>>8303103I have no idea what you mean by "today's standards", but the term you were looking for was probably "snap build", not "scratch build".
For what it's worth, Koto MuvLuv kits are designed to look good unpainted, some of them even have markings painted on the parts. They also have a lot of seams in fairly obvious places (which are not as visible as you might think if assembled competently).
