The thing is.. From what I've personally seen.. You don't get much complains if you are an importer and put new characterss, but if you are editing a regular character, it seems you have to do alot of work to don't have any complain.
This is true. I just imported Sothe and it's barely passable in my opinion. Half of his jaw is bound to his neck along with some problems with his pants (...that came out weird). Some people (I believe) are saying good job as a way to motivate me, which I completely understand. But those that don't really know are saying good job because they just see it and say "Cool, my favorite *insert character name here*!".
And on to Kyouma's second point that it's harder to make new stuff for an old character (recolors and the slow, but new trend of "Wii U" skins). One small mistake and everyone is up in arms (or multiple big mistakes and it makes it to that blog, although I believe entries can get taken down if the creator asks or something).
So much more has to go in to make everyone happy (even though you should really only go about making yourself happy, but that's a different discussion). That's why the furthest I'm ever going to go with textures is recolors for PSA's that I'm working on.
In the end, I don't think there's a right answer, but what Pik said is very true:
I guess we can say live and let live, right? The people who'll improve will, and the ones who don't have the drive will find something else to do.
