For one, DYNAMO's works (kinuk) have pretty solid depictions of Shou and Nazrin and range from serious to romantic depending on the book. Not for everyone, and some interpretations are taken, but solid enough.
Really though the works that get spotlight overseas are rather extremely focused because most works go through several layers of selection: getting noticed in Japan, being cosigned / sold in shops, getting imported, getting noticed overseas, getting translated, etc. And 99.9% of sold doujinshi read by foreigners are going to have been scanned. With all the filtering that happens along with the inherent tendency for doujin circles to be niche, tight-knit, and cliquey, of course you're mostly going to find the stuff that makes it through all that; especially so if you don't yourself delve into very specific artists and circles and the people around them. Even if something has the characterization and writing, also having good enough art for the work to get anywhere is another pretty big hurdle that is greatly underestimated. It's one thing to disparage how ubiquitous some kinds of works are and how popular they get, but really all this seems to amount to is "people don't like the things I like" applied to a very small subset of all works.
