As a bonus for the higher subscription tiers, here's the original image from ComfyUI with the workflow. With this, you can modify the prompt in ComfyUI and create your own variations of Yuma and the image.
To do this, you will need to download ComfyUI:
https://github.com/comfyanonymous/ComfyUI?tab=readme-ov-file#installing
Additionally, you will also need to download the corresponding Stable Diffusion model and put it in the ComfyUI/models/checkpoints folder:
https://civitai.com/models/315596?modelVersionId=354017
Then, simply drag the image (the png in the attachment below this post) into the browser interface of ComfyUI and the workflow should be visible.
While it should work, I don't guarantee any success though. ComfyUI / stable diffusion requires strong hardware to run properly, and there might be other ComfyUI plugins needed for the workflow to work (I haven't tested it on vanilla ComfyUI). Feel free to ask questions though if you are stuck.
