Skin texture

 In Photoshop open none and create a new layer, rename it guide and fill the background with blue, because it different colour to the texture. On the background layer press ctrl a to select all and ctrl c to copy it, press ctrl q to turn on quick mask and past the background in to the guide layer.  

Go to select modify border and choose 4 for the border width, so if I zoom out I can still see all of the lines. 

Click as vector mask to remove everything that I haven’t selected.

Right click and apply layer mask.

Use the lasso tool to select the area I want, then copy and paste it to the uvmap.

Use the lasso tool to get the skin from the side, paste the skin to the none map and click edit, transform and flip horizontal, so I can use it for my right hand side of the face.    

If the skin doesn’t fit, I can use wrap to transform the shape of the skin.
 

After all the skins are in place, I can use the patch to join different part of skin together.

Use the lasso tool to copy one part of the skins and paste it to fill in any gaps, I can turn the opacity down to help me see which part it overlap and use the eraser tool to erase parts that are overlapping.   
 

If the gaps are too small I can use the cone tool to cover it up. 

Do the same to the ear by copying skin from the photos.

Whole face 

To add the inside eye skin colour, I have use the normal map to see the folded inner layer and highlight it using the brush tool.

Hide normal map and I have choose to use the colour that is similar to the skin inside my eye to fill in the gap. Use the blur tool to finish off.  

After I have finished the skin texture, I discovered that the ear skin colour doesn’t match with the skin on the face. So I decided to go back to 3d max, open edit in the unwrap uvw, scale and move the ear back in to the head, then weld the vertices of the head and ear together.  Render and save the new none map.
