Using tags that are more like those from the auto labeling, along with the "bwc", "bbc", "swp" and "sbp" tags and "bigger ..." and "smaller ..." I also tried shuffling some of the tags, but not the most important ones.

If you want a particular size difference in the image, I suggest you put the opposite size difference in the negative prompt.

I tried a somewhat bigger network in this case ... we'll see how it turned out -- whether it could learn all the "types" as well as the "difference."
