Frankly there's so much choice my head started to swoon at some point. I'm still not sure I managed to chose the coolest skins, I really like the cobalt blue color of the skin you linked but there was't one with a more "boy" oriented image, so I had to pass. In the end I opted for Flying Tree Black (matte) ,Flower Of Fire (glossy) and for the Sacred Honu (matte), cause of the beautiful celeste color . I also like the Van Gogh-uish Waterfall and many more, but, as I said, at some point you have to pick one and stop lokking at others to avoid regretting your choice
Damn, wish there was a cobalt blue skin "for him".
