It's different from anime character, sadly. Such parts as eyes, brows, figure, mouth placement/size, skull shape, and other details are different. So, it's more like "Hestia cosplay". There a lot of inaccurate arts in internet, so I'm not surprised.

Yeah this is definitely more useful as a hestia costume cosplay than a character LORA

hmm. It's useable, but I think you made the big mistake to describe the character too much in the captions. As a result, Hestia's features won't appear unless you use ALL the triggers, which shouldn't be necessary.
It would be nicer to not describe her at all in the training, you should describe only the things that has changed in comparison to her default look. If nothing has changed then "1girl,solo" for example is enough
