I did a few artstyle LoRAs before, but this is my first character LoRA, so the results might not be the best.
From my testing, a strength of 0.8 will yield the best results.
I made sure the goggles were optional, so if you want her signature headwear, use the tags "goggles, googles on head, headphones"
I'd recommend you try the tags "jacket,orange jacket" if you want her V6 look
