Honestly, I don't think he'll offer SD cards even with the highest Patreon tier (which is actually quite cheap in my opinion), and I'm not going to attack him or anything. Everyone runs their business as they see fit, and if there's no demand from the community for more content through the subscription, I think that's a separate issue.
My point is that after checking Pixiv and Kemono, I've noticed that, Trsaren only offers renders and videos of his scenes from his MEGA cloud. Although I would suggest he use better terminology because when you see "Megalink," you think he'll offer EVERYTHING: SD cards, character cards, mods, coordinates, and renders with videos.
I think that's perhaps my only observation. As for everything else, if anyone is paying for his Patreon and corrects me, I'd be equally grateful because it would give me a reason to subscribe. xD
But, idk, the model itself is a creation of CinnamonTea (and it's unlikely I'd disagree unless they have proof of an even older origin... I've only been involved with Koikatsu since 2021). Basically, all the female models he's made for his SDs use that body template.
And it's no surprise that in many cases, content creators use other people's creations as body templates without proper authorization. They think this might get them to the original authors faster. And they're not wrong.
Although, honestly, from my limited interaction with CinnamonTea and KrUnCh, I've concluded that they aren't people who complicate their lives with problems or negative feelings like envy. They usually allow the use and modification of their cards as long as there's a mention or a link to the original model's publication. Which is a very small price to pay (or basically free) compared to what you can earn if you know how to use Charastudio well, even if you're less skilled at creating character cards.
Lately, both Cinnamontea and KrUnCh have lost their original pixiv accounts (the ones that contained all their material, basically), and at least on CinnamonTea's side, there doesn't seem to be any interest in re-uploading the lost content, creating new SDs more frequently, or continuing to engage with the Koikatsu community.
In his last post on his current Pixiv account, he stated that he felt overwhelmed and powerless for not having been able to recover his previous account, and I don't blame him. Having followers, reach, and a track record on the site is also beneficial, especially if you partner with Fanbox. But there's a problem here, a big one: CinnamonTea and KrUnCh didn't charge for their content; it was all free, and even so, their accounts were taken down (and they used censorship because I also know there's a Pixiv rule that has basically removed a lot of content that didn't actually violate any sensitive topics or the rules themselves).
This is something I really detest about that platform. I've even seen sensitive and bannable material in the Wayback Machine archives (maybe they saved it for evidence or something), and when you use that link in Google, those posts are still there. A real contradiction, or is Japan trying to tell us something?
And yes, I deduce and suspect that both content creators are from my country. continent, because I've seen them handle Spanish properly in X. Well, that would be all; anyway, I'm already warning you, even if you don't like a card you see on pixiv, I still suggest you download and archive it, Cinna and Crunch haven't been the first and much less the last content creators to suffer these bans due to reports or pixiv's own hollow rules.
