I just make screenshots of every detail when creating a character, but I guess that doesn't help here. Maybe for next time.
In case you don't have anything else, PRT Scrn keyboard key works and paste into an image editor to save, since Fraps can't capture BG3 DX11 mode.
I'm using GShade, which is a Reshade variant, to make screenshots,
