Custom Models for character workflows crop full-body generations

I wanted to share an observation after testing Firefly Custom Models with a character.

In my case, the model keeps the character identity quite well, but I’ve noticed framing issues. In full-body images, it often crops the mermaid, even when using prompts like “full-body,” “entire character visible,” or “not cropped.” I also tested different aspect ratios, and the cropping still happens.

In the training set, I used “full-body mermaid” in the captions for the full-body images and “portrait” in the captions for the portrait images.

In portraits, the framing is closer to the training set, but when stars are included, they also tend to get cropped. If I explicitly ask for stars in the prompt, they are included more cleanly, but the portrait still ends up feeling closer than the way I trained it.

I noticed the framing improves a lot when I add a composition reference, so the issue does not seem to be character consistency, but rather framing in the generated results.

I’m attaching screenshots of the training set I used and some test results for reference.
