Good work but there are a few issues:
- the face has almost the same color as the hair. You should correct the face's color back to flesh color.
- add some stray hair arround to avoid an unnatural 'perfect' hairstyle.
Personally, the first thing I would fix is the pervasive orange color (...almost certainly due to a combination of tungsten illumination and fading of the dyes in the print / slide). Only after I got close to a reasonable skin color would I start to deal with the repairs to the background and other areas.
Bahhh, humbug ... I just looked at mine again. I''m not happy. I was so concentrating on the colors, I see that I removed too much texture and shadowing from her face. I don't want to leave the original texture intact in that area because it has so many jpg, paper creases, and other artifacts, so I probably would just steal some texture from another face, LOL.
