If you don't the see same style as on Miku's picture, try to increase the weight. Start with 0.7-0.9
For the exact style from pictures above, add "amazing face, perfect face, Detailed" to the prompt, although, I'd say that use of facefix/adetailer is REQUIRED.
If generating on Civitai does not provide good relults, use other services.
This LORA is available at Pixai.art and Tensor.art
