Fast Chroma w/ Upscaler, Refiner and Face detailer [Low VRAM]

So, here’s how I roll: this workflow generates a little Chroma image with txt2img, upscales and refines it for some extra polish with FluxRefinerV1.1 with img2img, and gives faces a nice touch-up (Face Detailer). On my trusty laptop (rockin’ an RTX 3070 with 8GB VRAM and 40GB RAM), it makes a 1120 x 1120 pic in about 180 to 280 seconds —depending on the prompt, as I said in my previous workflow, I’m new to ComfyUI, so if you’ve got any tips or tricks, I’m all ears! On the bright side, at least I didn’t make a huge Spaghetti Monster this time!
