With this workflow, you can easily upscale any image with Flux models. Simply select which image you want, adjust the settings (in pink and blue), enter a prompt and your are good to go.
This workflow features an Image comparator that lets you compare your initial input image and the upscaled version with a slider. There is also a Power Lora Loader with which you can add many LoRA's without creating extra nodes, thus you safe a lot of workflow space.
