I don’t usually go for composite images, they generally leave me a bit cold, but I just had to post a link to Mattijns images.
I’m not sure how he creates these images, but they are simply stunning. You can find his work here.
Mattijns Playing Around Flickr Set. If anyone has any information as to how he creates these images I would be very interested, but I would guess there is a lot of digital art work going on here before he adds his composite images.
