Agreed, HelixJack is almost exclusively Toony style. Though I disagree about Trunchbull – though it’s been a few years since I last check their gallery, what I’ve seen from Trunch is either a style imitation of Kemono Inukai or a more painterly style possibly inspired by early-mid 20th-c. pinup paintings.
This one in particular though, being a very straightforward Furryfied version of something, I obv had to post here :P

I can’t say I know timelines, I will agree the latex style of Tunchbull definitely looks like Kemono Inukai. The only gallery I know of that Trunchbull still has up is https://www.pixiv.net/en/users/13619866 They purged everything else.
