This seems to be a reposting account so I removed the artist credit. Also, I feel like this might be ai-generated.
As for AI, to me it definitely doesn't look like AI (did some polling on the Discord too with similar responses), as well ast the poster seeming to be opposed to it.
Regarding it being a repost account, I suppose I can't rule it out but to me it looks like a relatively normal artist Twitter account posting works with various degrees of polish. I'd like to hear what makes you think it's a reposting account, I may very well simply be missing something.
