The best way to learn, for a lot of things AI gen included, is to copy someone who knows what they are doing then piece together why exactly what they do works.
I personally use NovelAi which costs some money, but I have heard that some people download Stable diffusion then add the 'waifu' model.
If someone is starting trying to generate hypno content I would go with a simple prompt, copy and paste:
{{hypnotized girl}}, {{{glowing pink eyes}}}, {{{hypnotized expression}}}
With quality tags on, undesired content set to none, and the model set to anime(full) the with the following negitive tags:
lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, jpeg artifacts, broken body, extra limbs, amputee, conjoined limbs, Siamese twins, incomplete, pubic hair, watermark, body horror, horror, greyscale
With that you should be able to get something good every 1 in 5 gens.
Here are some good inputs I've found.
if you want more than one girl, use {multiple girls}, the problem with this is that novel AI has a hard time with limps the more people there are.
{fantasy} makes it so that you get different girls instead of clones.
{NSFW} is usually the only thing you need to type to get nudes.
{full body} should be obvious.
The less tags there are in the data base the more {} you need to use in order to see an effect.
The way I think about a prompt is that I divide it into four parts:
Main target
Background
effects
style
If you have at least one decent tag for all of those you will usually get something nice looking when it turns out good.
Lastly, don't be afraid to edit. When I get a good gen but there is an extra limb (or anything else) you can roughly paint over the bad part with the background then use the 'enhance' feature. Lastly, I up res using a different site like
www.aiseesoft.com/image-upscaler (or any other), because AI can only gen relatively small images.
Don't be afraid to experiment.
Hope that helps.
