I would call this a High Key Image GJ.
It isn't just an image done as a high key.
There is a lot of air brushing, painting and so on as well
I feel your pain. Digital compositing is a pain but fun. At least you had a good picture to start with, I've always have to fix photos that people take themselves or by amateurs and Fix em a Ton.
Like this poster. Its ok, but the photos they gave me to work with were wretched! A couple of hours fixing and compositing got this small band a decent poster. They liked it and it was alright in my eyes.
