I think you somehow managed to take a fair amount of her tan away... whether that was intentional or not is another question but i would have left it, and yes a bit of work on the hands would put the cherry on the top.

www.fluideffect.com - is down at the moment - but from memory their portfolio stuff has a lot of before and after shots of airbrushing (portrait and full body)... if you havent seen it already (it came up in a thread ages ago) then you could get some tips just by observing how the pros do it i suppose :)

In every stone sleeps a crystal.

Man is the dream of the Dolphin"
