There are so many amazing workflows here, and the more tools you have in your toolbox, the better. That being said, I find myself using this workflow more than anything else. I'll often take the output of this into other specialized workflows. It's my own preference to keep this base workflow clean and straight forward as opposed to having a huge, do everything workflow. As such this workflow is targetd at hobbyists who are trying to create or recreate very specific images. I work primarily on DnD artwork or Anime inspired images.
Other workflows I have include checkpoint to checkpoint refining, detailers, inpainting, flux comps to sdxl, region cutoffs, and so on. If you'd like a version of this workflow with functionality groups for all of that, let me know, and I can take a crack at it. That said, there are a ton of do everything everywhere all at once workflows already out there.
I very much stand on the shoulders of giants that have gone before me and all credit goes to those who have made the workflows I've learned from.
