It still struggles with bellybuttons among other features. It's something that can be improved with editing and patiently re-trying, but I don't always have time.
   

   

It's been fun but I need to turn down the horniness a bit. Pregnancy is sexy but it's also beautiful.

Using a merged model again, 90% SD 1.5 and 10% NAI, to give photorealistic content a slight enhancement from the precision and artistry of the NAI dataset. It's hit and miss. 
   
   
   

A work in progress. I still need to figure out a process for good bellybuttons when the AI isn't cooperating.

   

This one took a lot of work, both tweaking prompts and retouching, but I learned a lot from the process. Enjoy.
   

came out great man, thanks for sharing

Holy moly those are super smooth! I love seeing images of girls with varying belly sizes. How'd you do it?

As the meme says, That's the neat part, you don't! The AI looks for what you tell it to find in pseudorandom noise. For text2img the composition is largely determined by the random seed noise. I generated a batch of 4-8 images at a time along the theme of "girls in a sauna" and see which ones could be developed further. Most of the outputs contained defects that were dealbreakers, but this one really stood out as having potential. It was quite frustrating at times as minor tweaks to the prompt can completely destroy the composition so I'd have to try a different approach. To begin with retouching just made things even worse but I was able to tweak the parameters to let the influence be more subtle. 

For control over things like belly size, you can use img2img to strongly influence the results.

Playing with a concept of iconic film scenes, it's far from ready to publish but seems promising. Use img2img on a film still and basically describe the scene in the prompt but with pregnancy references. Needs some tweaking, denoising strength needs to be fine tuned as do other parameters. Might be a future project.
   

Another unfinished one, more festival girls.

   

Another beach pic. I need more practice in using infill to extend cropped pics. It can be done but at present it's far too dependent on luck for me.
