A simple Krea 2 workflow.

About the V2: Besides some optimization, I added the ModelMergeSimple (git clone https://github.com/isiwork/ComfyUI-Krea2-Model-Merge) node which is self-explanatory. A strength of 0.5 gives a perfect mix; lowering the strength allows for more influence from the second model, while increasing it gives more influence to the first model.
