This workflow is nothing special, it's just what I put together for myself after messing around with Z Image for a few days. It uses a custom node to enhance the variety in the image generations. You can turn it off if you don't want to use it. If the workflow helps a single person, my mission is accomplished :)

Download the custom node here

Extract the contents of the zip file and place the SeedVarianceEnhancer directory in your ComfyUI/custom_nodes directory. Launch or restart ComfyUI.
