Hint: this version is NOT very good at controlling the dragon's color, see examples.

Most examples are generated with the same prompt and almost the same settings but on different checkpoints (not in sequence, some are pruned version, so it's not easy to fully reproduce example images):

AnyPastel v4.5
Anything v4.5
Anything and Everything v4
Colorful v23 (with CutOff Extension)
Deliberate v2
Dreamlike Diffusion 1.0
Dreamlike Photoreal 2.0
DreamShaper 3.32 baked vae (clip fix)
DreamShaper 4 baked vae fp16 (with CutOff Extension)
HASDX
HASDX realistic
Pastel-Mix Stylized Anime
Protogen Infinity v8.6
RPG v4 (with CutOff Extension)
verisimilitude dark

PS: Works well with Ori-ArtStyle Dreamlike LoRA, which gives nice shiny texture to dragon scales (examples generated using ComfyUI, didn't find a way to reproduce in A1111)

PS2: It seems that if lower the strength and use less prompts (especially the trigger word portrait tends to introduce strong color patterns), the color controlling will be better

PS3: Try use CutOff Extension to further control the color
