A normal selfie taken in your living room probably won't give you quite the same effect. Creating such an image begins with lighting techniques and use of manual exposure with a camera. The lighting is directional (from one side only), and the photograph has been exposed for the highlights, leaving the shadows much darker.
It's going to be harder to achieve that look with a phone camera selfie, although not impossible. If you can, arrange some lighting off to one side, and take a few shots until you get something that looks usable.
Once you have a usable photo, the colouring can easily be adjusted later in Photoshop. Here's an example using a photograph I which I took, shot in a studio, using these techniques.
Here are some steps which could be used to colourize the image, without creating too much posterization/sketchy effect:
- Add a Hue/Saturation adjustment layer, select the "colorize" box, and change the hue until it's a blue-green colour, and perhaps increase the saturation a bit.
- Add a Levels adjustment and crush the shadows to make it high contrast.
- Add a Channel Mixer adjustment, and select the blue channel and adjust the channel sliders as shown below or until you get some separation of greenish highlights and bluish midtones and shadows.

As for adding a background, there are plenty of tutorials on the web for that, and some questions which cover the topic here on GDSE.
