Also interested in any tricks to make the decapitation more pronounced, because most of the time the neck turns out too small

Use inpainting if you want higher details on cross-section, the model only focusing on the masked area to redraw during inpainting. You can also draw on the cross-section beforehand to define the muscle, bone, fat, trachea ect., then inpaint the area with low denoise value so the model will use your "guidance" for redrawing.

This. You also can literally crop the cross section from any art you like add it where it should be in Photoshop and then inpaint over it with low denoise.

yeah if you let the model do it, it will generate a very thin neck, here i've inpainted the throat hole, and slowly merged it in.

One way is to grab some existing image like even real photo photobash it with your image then let ai to process it. into desired style
otherwise no way to do without training lora
qwen image edit may work great here

This is exactly what I have been doing with img2img. My first experiments were with a few favorite guro images and an avatar my partner created. It's been difficult to rework photographs.

I tried to make a photo of my partner be more bukkake-tastic, but struggled a lot to get any good results. I might try again. I took some photos of myself using a severed head sex toy I own made of TPE and got something ok with one photo, and struggled to keep the gen stable with the next. It's been a lot of work getting anything out of it. The AI very much wants to either generate nonsense or make it's own unrelated picture to what you're asking for.

well considering photographs actually the way i tried it is you take some image with gore or BDSM then ask AI to outpaint it with desired character , then you can put it into video model and make it rotate character to some extent into another pose and grab desired frame to reprocess

That's really clever! If I can ever get the video AIs to work on my PC I'll give that a try.
