From Prompt to Printed Sculpture
Step 1 - Prompt
@Gesa: Greetings from Germay. I'm not very creative, so I mostly used your prompt with a few small adjustments. I wanted her headpiece to resemble a swan.
So I used at GPT Sora the prompt: "Please create a simple table top figure of a winged creature that looks like a swan. The whole posture is graceful, dynamic, with bold angles and shapes. The costume is relatively tight, like a partial armor, but with open parts where the slender figure of the creature is visible. Also, above the layer of tight armor it wears a flowing layer of cloth that emphasizes the movement and dynamic of the scene, but the outline of the creature is still clearly visible. It is not hidden behind the flowing cloth, since it is just one detail that makes it stand out. The creature itself is very beautiful with striking features. The overall style of acessories is a mix of: otherworldly, alien yet elegant, with hints of ancient egypt. The image should only contain the creature. Solid white background, no shadows, centred figure, 20% padding"
It actually turned out pretty well, but the figure had only one wing. So I simply added an extended prompt: 'Try to make the same version, but with two wings' and this nice result came out:

Step 2: Turning it into 3D
I tried several of your suggested tools, and the best results came from 3DSparc, the Hugging Face tool.
I imported the model into Blender 4.5, where I applied optional some minimal coloring.

Using your suggested 3D Print addon, I prepared the file for Cura and exported it for printing.
Step 3: 3D Printing
At our public city library, they have a 3D printer available for public use. Coincidentally, that same week they held their monthly 3D printer training, which meant I was able to use the printer without ever having used one before.
Here’s a little snapshot of the printer in action.

It took 35 minutes to finish—unfortunately, one of the arms fell off, so the result wasn’t perfect, but still really cool to see it come to life.
Thanks for the awesome workshop you shared with us!
