First of all something personally important to me. There is already a LoRA for Surtr with all 3 outfits as well made by a friend of mine. The person who requested the LoRA didn't like it, I personally can't judge it, since I didn't try it (I'm busy as it is with my requests), but I do believe that it is good. And now that I made mine I feel like an as*hole, so if you like the character I would appreciate it if you check their Surtr LoRA as well and decide which one you like more: https://civitai.com/models/495306?modelVersionId=742914

The results of your generations are dependent on the additional LoRAs, weights, and models you use, so it may not work or come out as consistent as my sample images.
