The LoRa in this example is "Queen Grimhilde (Evil Queen) | Snow White | 3 Attires" by Desenhista 6.0, https://www.seaart.ai/models/detail/ctapacde878c7393lc80
LoRas are trained to produced specific styles that mimic the visual training data their dataset is based on, one of ways to add variance to your images is to use LoRas with negative strength to remove the LoRas characteristics from the image.
Here are two examples of prompting for Queen Grimhilde to smile in a horror manner, with the LoRa at positive strength.
This LoRa does a great job of capturing the essence of the Snow White villain, recreating the wicked queen.
The technique for image variance simply requires lowering the LoRa strength scale below the 0 threshold. (-0.1 to -1).
__
LoRa strength is located to the right of the generation button, in a menu titled "LoRa" with a sliding scale for strength. (-1 to 2)
__
Below are examples to highlight the changes to the image due to the strength of the negative setting.
These two images were made with the same prompt, and the LoRa strength set to -0.1
__
LoRa strength set to -0.5
__
LoRa strength set to -1
No other LoRa was used in this example, just using this LoRa with positive and negative strength settings, and the SDXL model will produce all of these varied results with the same prompt and same settings.

Using two LoRas at -.5 strength further varies the output. ( https://www.seaart.ai/models/detail/fcdbfa84acd35404705c41f317ec5aaf )
SeaArt allows the ability to use multiple LoRas at once, it is up to you how you decide to adjust the strength settings for each LoRa. You have to ability to make all of the LoRas positive strength, all negative, or a blend of some of both. Each LoRa has adjustable strength levels to further refine the style and type of image you are trying to achieve.
These examples are with the same prompt, each was made with three separate LoRas at various positive and negative strength settings to highlight the range of image variance. Further adjustment can be made from altering your prompt as well as selecting LoRas in different art styles. ( https://www.seaart.ai/models/detail/cmubamde878c73dehdp0 )
