[Awesome] The visual impact brought by high-level PS

I don't know which master created the following several PS pictures. The professional skills are simply so amazing that I worship! What makes us feel so visual shocked for this picture (the thumbnail is not very clear, please click the following words to browse the large-sized original one)? Are the two unrelated objects being placed together? Or is it the author's superb PS skill? If I have to choose, I would go with the latter. How about you?
