These are very sweet, and love the embroidery details!
All of the SDXL models are too airbrushy plastic to my eye, but you can't argue with the hand quality over the older 1.5 models. One of the things I'm wanting to try is to start with an XL model to get the basic pose structure in place, then finish with the grittier and more realistic 1.5 models. That introduces a whole new level of adjustment knobs to play with!
I never use models trained on specific people or ask for celebs in my prompts. This is the base Flux model plus a Gil Elvgren style model. I can see the resemblance though, but it wasn't something I was aiming for.
