A lengthy workflow to create a 2k image with SDXL while attempting to fix faces and hands.

Download it from: https://raw.githubusercontent.com/bash-j/mikey_nodes/main/2k_face_hands_extensive.json

It uses some nodes from my https://github.com/bash-j/mikey_nodes

And nodes from the following:

https://github.com/ltdrdata/ComfyUI-Impact-Pack

https://github.com/ssitu/ComfyUI_UltimateSDUpscale

You will also need to install the yolo face and hand models and the sam models, which you can install through the manager extension.
