The biggest thing regarding artwork is the game-maker isn't the guy making the art. This isn't like Tavern of Spear where the game's creator (Caro) is also an artist, so he doesn't have any outside costs for the art (MOSTLY, since I know Dangpa also does CGs for ToS, but my primary point stands: Caro is an artist, Hyao is not).
Hyao isn't an artist, and on top of that, he's already had multiple artists, which also means older content with a different artist suddenly getting new art would be quite, jarring, to say the least. ZoroJ did the art for the Nymph IIRC and he no longer works on the game, so if Nymph got new art, it would be from a different artist, and yeah it'd be quite weird for sure.
As for missing artwork, females have never been a focus, so the fact there's any artwork of them is a blessing (for those of you into them). The pair of male bandits that assault you also didn't have artwork for quite a long time, and now they do. Female Bandit could as well one day, but the game has a massive M/M bias, so don't hold your breath.
"Creatures in the woods"; once you unlock the Wolves' Den, you have access to additional werewolf scenes (Beta/Alpha) as well as scenes with the wolf leader. If you mean "new artwork of them doing things", I'm not sure what you expected; LD has been like this since the start where the art is just sprites and it's primarily text-based (you even said it yourself).
> "Wolf stuff"
I mean you can top the wolf leader if you want. Also the wolves only piss on you if you lose the fight against them and you didn't make them horny enough. What would you prefer? A gore-y murder porn scene of getting mauled to death like you'd expect from Tavern of Spear? What else can Hyao really do there for a non-porn way to lose to them? You're also talking about one of the oldest zones in the game on top of that.
You mean you couldn't find it erotic because you'd submit to a monster and be met with a *graphic* depiction of how that monster murdered you. To this day I refer to ToS as "Murder Porn" because that's essentially what it is. Sometimes you get porn, other times you get murder. Sometimes you get both! (like the end of the first arc; I won't spoil what it is but submitting there will result in you being fucked by the BBEG of the first arc, followed by a *GRUESOME* murder scene of MC dying; like yeah it's more 'realistic' of what would or could happen, but it's better to just leave it ambiguous since THIS IS A FUCKING PORN GAME FIRST AND FOREMOST???).
