This is my Lora for the fantasy race Seeq from Ivalice.
Best way to prompt probably would be by generating full sentence prompts from tags with ChatGPT or some other AI. This lora works best with proper sentences and language.
I suggest integrating the (leathery) skin color, whether it has a (nude) topless upper body, the horn form or hairstyle, the attire and gear as well as other small intricacies like size, expression, stance etc.
The chosen medium is important for the prompt. Realistic depictions or photography will probably achieve poor results. For anything even remotely realistic I'd use the prompt screenshot. Otherwise digital illustration works best.
For negative prompts these are some I would always use: deviantart, anime, hands
Have fun!
