After this I rebuilt the image by using different images since the skin of the kid is quite irregular. I used concrete maps and dirt maps to give it the desired variation. And this is the result I get...
For the jacket and pendant I did the same. I used the image I got from the photograph and rebuilt it. This might be cheating for others but I rebuild all of them. The initial projection is used to see where the scars and small things lineup.
For the eye, I didn’t use the textures. I just used a ramp with a marble fractal for the veins. Since I don’t really see it this way works. And it’s easy to manipulate the ramp.
After getting the texture for the face I bring it back to Photoshop to make a bump. I use high pass for this then I brought into ZBrush too see where the scars lineup.
Then I save the big scars and rebuild the pores and fix the scars along the way. I do this in ZBrush using the bump viewer material. This is faster for me than subdividing for getting the details.
Lighting
I suppose, this is the most important stage because this brings life to the images. So what I did for this image is, I compared the one I edited in Photoshop by removing the shadow and highlight. This way I can see the different images with and without light.
Then I used an area light to make my sunlight. Then I made bounce lights for the red light bouncing from the back wall and also added fill lights as well.
