Seth from Deltarune. I recently finished chapter 5 and I love this character so much and I just had to make a lora of them. All of this was trained with fanart, so there will be different depictions of how the character looks for others. I choose images that had the most consistent look and wouldn't mess up the overall look of the character when generating them. The lora works mostly good. You might run into issues where the nose still generates. Everything else works well from my testing.
I know I said in my last article post that I was taking a hiatus from making loras, but I am making an exception here due to how much I love this character and wanting to do this immediately after finishing Chapter 5.
Positive Prompts: S3thDR, ambiguous gender, humanoid, purple hair, long hair, black eyes, dot eyes, no pupils, no iris, noseless, buckteeth, light-purple skin, nerd
For the outfit: magenta coat, long coat, lavender tie, lavender scarf, lavender pants, white shoes
Optional: black eyebrows, short ponytail
No need to put "glasses" in the positive prompts as it will generate them normally. If you do decide to put it, then the character's eyes/facial structure will look entirely different. Put "black eyewear" in the positive prompts instead if the glasses do not generate instead if they don't show up while retaining the look. Put "glasses, eyewear" in the negative prompts if you don't want eyewear generating on the character.
