Apparently the guy who did most of the NWN character art drew some portraits that never got implemented in the actual game. Some of them are pretty damned amazing, and I am certain most of us can find uses for them. I will upload them here as I crop and resize.
Tella, I am not sure how to convert .JPG files to .TGA files, so if ever you find the time and inclination for it, feel free to make these into useable portraits.
