Yes, pakeha, Akiane Kramarik used a model. Please read about her in:

Here is an excerpt from the webpage:
"I always think about Jesus and talk about Him," she says. "I was looking for a [Jesus] model for a long, long time, and when I couldn't find anyone, one day I suggested to my family to pray all day for this model so God would send the right one." The day that they prayed, a very tall carpenter—yes, a carpenter—came to their door looking for work. When he showed up, Akiane nearly fainted. "I told my mother that that was him. I want him to be my model," she recalls.
The carpenter agreed to it at first, but he called a week later to back out.
"He said that he wasn't worthy to represent his Master," Akiane says. "He's a Christian, and he's a humble person. But I prayed that God would change his mind and that he would call back." And the mysterious carpenter, who wished to remain anonymous, did call Akiane back, saying that God wanted him to pose for the painting, although he felt it was unusual.
Akiane took pictures, studied his face, made sketches, used her imagination and photo references, and the result was the "Prince of Peace."
I sent a picture of the “Prince of Peace” with a Christmas card to the Philippines, and asked the spirit of Ama when He comes if that is how Jesus Christ looked like. On New Year’s Day, Primitivo Tabo, Jr. of NYC called me and said that Ama said that it is. In one of my tape recordings, Ama revealed that Jesus was 6 feet 8 inches tall. Akiane may not know that the “very tall carpenter” she made as model was Jesus Himself. Is there anything impossible to God?
