Help Wanted: Noob with Stability Matrix Inference

Hello! 🙋‍♀️ I am a SD noob, but I am liking my results than MidJourney so far! I also like that there are a lot options with SD (once I know how to use it 😅). I am using Stability Matrix to run ComfyUI through their Inference tab (screenshot below). Does anyone know of tutorials or methods to get my faces to look better (also screenshot below). From what I'm reading, it seems Stability Matrix is fairy new? So I'm struggling to find existing Reddit threads or tutorials about it.
