Some positives and negatives here.

I only tried this with snowpony and the autismmix checkpoints.

Positives are this seems to get VERY good Shalltear specific expressions, like faces you would actually see her make in the show. The artstyle is extremely accurate in certain checkpoints using the prompt of anime screencap. A lot of images I've gotten look like they were officially right from the show, I'd have to say closer than almost every other Shalltear lora I've tried just because the expressions are actually hers and the way it's "drawn" looks spot on.

Some negatives are it seems to be very difficult to generate any form of nudity while also having her stay partially clothed. Sometimes even taking out all the clothing prompts and adding "nude" still generates some of her clothing. Doing any kind of "position" while having a facial expression seems to heavily focus on her face and zoom in too much, to the point that it's actually ignoring most of my prompts just to generate the uppermost of her body and face and nothing else. Sometimes it will generate what I'm asking, but it strangely only puts most of her in frame while giving you the feeling that it's cutting out the peripheral of the image, when it does this, it looks like when you look at an image that's zoomed in too much (I've tried quite a few different resolutions and aspect ratios and can't seem to alleviate this, and I do not usually have this issue with character loras). Finally, the bell-shaped dress seems to generate strangely, always generates as a blank and plain color with no details like the actual design has; you can even see this in one of the example images. It's more complex looking than that in the actual design (seen here: https://static.wikia.nocookie.net/overlordmaruyama/images/f/fe/Shalltear_Anime_Updated.png/revision/latest?cb=20220209052132)

Even with the flaws I've noticed, I really like this one. I hope you do a Neia Baraja lora from the upcoming Overlord movie which is in theaters in some places right now, I suspect you will have one of the better ones if you do.

Last I wanted to say that I personally feel like people should really only be making character loras as perfectly accurate to the original artstyle as possible, and nothing else. If you want to put a spin on a character lora, you don't need to. If you make a great character lora in the style of the original art, you can leverage checkpoints and style loras to accomplish anything further. I just don't understand the point of people making a character lora in an artstyle that isn't the original, as the end user can accomplish that. This one is very good at accomplishing the original artystyle.
