bruh, you dont gen another full image, you INPAINT a small part...
mask etc smaller for hands, sample steps can be like 11-15
width/res only like 7682 or 10242
denoise biggest error, you need high denoise to fix stuff.
usually 0.7 to 0.8, above 0.8 it gets crazy and below 0.7 is usually to keep details from original (like shape ok, only fingertips changed)

pls tell me your prompt at least was short...
