You may want to add either more background tags and weight for them, or "white background" to the negative promp since this hero just came out and there are not many pictures with her, so i had to train lora on white background blender screenshots. It should work anyways, but background may be too bright sometimes.

This is my first ever Lora, but since im in love with this chracter, i put a lot of work into this one, hope you like it :) Please upload your results here, so i can see how well it works and what needs adjustmnets
