One really nice edit that i across was this :
I really like it because of the colouring and pattern technique that is used to create quite a dark and gloomy atmosphere. This reminds me of the harry potter poster which has also used this, by giving it a dark or gloomy pattern as if its layering over them.
I tried this myself by adding both techniques and this what my one came out as.
Here i just got the original image of the girl and put another image over it which was of lots of fast moving lights. I then got a pattern PSD to put on top of it, to give it a medal like texture.
