I've been searching unsuccessfully for a duo of portraits for Baldur's Gate.
Its art is what you'd expect from most of the default BG2 portraits that can be found all over the net. From books, as I recall.

The first is a female with her eyes closed. She has orange long hair and light blue skin, and wearing a white robe.

The second is a portrait of a male dwarf with a long red beard and his gloved fist showing next to his head. His head is bald and has a crack in the centre, running from his forehead to the back.

If anyone has these or has found these, I'd be very much interested in obtaining them.

I have not seen what you describe but you could take a few hours and look through Portrait City

Awesome.
I found both of them there.
