Uma Sensei (Amakuchi)

Uma Sensei is a furry OC own by the artist Amakuchi. It will nail the character look well, but there are some issues to be mindful of such as eye artifacting issues, her eyewear/glasses being present even if you don't prompt it, the glasses themselves generating poorly in side angle views, and sometimes it'll have her eyes closed even if you prompt the character looking at anything or not even prompting "eyes closed" at all. Due to all of this, it is best to keep the lora strength at 0.9 for pose flexibility, art style consistency, and to help mitigate those issues. You can still get good results at normal strength but you'll run into those issues I mentioned a lot more frequently. Monochrome generated images will come out better than images with color due to most of the image dataset being in monochrome. Put "slit pupils" in the negative prompts if you are still having ugly eye artifacting issues. I noticed when putting that in the negative prompts it helped generating eyes easier. Her black pupils are a bit thin and oval so this is probably where the issue is coming from. Hi-res fix is also recommended. Finally make sure to put "text bubble, word bubble, speech bubble, word box" in the negative prompts so those don't randomly generate.
