There are several ways to achieve this, however each photo may be tackled slightly differently, but you might find this small tutorial helpful.

In your example, the one on right does not seem to appear realistic, but rather "doll" like, i think a bit of colour correction would help to make it look a bit more human like, the colours seem a little too bright to me.
With a little practise i am sure you can acheive the look you require. PLease feel free to post any updates.
