Below, the video of my full rebuilding of the background on Photoshop in less than 20 min. Any other adjustments (color, etc.) were done in Aperture app. Note that Photoshop is totally useless for me in 99.9% of the photographs presented on the site; careful not to be blinded by his name… The video is not commented, for any question, I would enjoy to answer you in the comments section of this post.
