Original image

step 1 of 3
The dress is made out of the ribbon from the source, layer style then changed to Luminosity.
Her wings were then made out of the circles in the ribbon, with LOTS of layers and modes mostly being Pin Light and Linear Light. The glowing fairy dust around her - like the wings, but only two layers and a little more glow :)

step 2 of 3
Hue/Saturation then changed to suit the night scene, a bit of Burning Tool on the corners to support the illusion of light coming from the inside of the house.

step 3 of 3
p.s> the tree trunk is made from the source image as well

Final result
