On second viewing, can I ask is this actually lit? There looks to be some colour bleed in to her jumper at the bottom of the frame where she's leaning on the barrier/fence. looks like it's maybe masked and used a day to night type of technique to tone it in post?
Hope you don't mind, you've got the allow edit flag set to yes, I've done an edit of the image it's fairly quick and only on the low res jpg so not perfect but just an attempt to tie in the colours and eyes.
I've obviously cropped it to take out the bit she's leaning on. The main edit is to add a solid colour layer set to overlay sampling the purples from the background shadows and the using apply image image on the layers mask and inverting it to add the colour into the shadows only. I did a slight levels adjustment on the mask just to control how much of the shadows were targeted.
I also desaturated the eyes a bit and added a bit of a fake catch light to try and make them pop a bit more, oh and some fake steam from the mug, because I like fake steam coming from mugs.
If you like it and want the psd just let me know.
