Well if cutting and pasting visual components to create a pretty picture is your idea of a "landscape" then indeed it is too easy. I suggest you quit while you are ahead.
The reality is that the make believe images you constructed illustrate a make believe world--one that has been shown before on countless insurance company throwaway calendars over the past 60 years.
These are not real landscapes, especially in 2013; they are shlock.
Recreating ersatz versions as you've done, without having one's tongue firmly in cheek, and expecting to be taken seriously as your modest title implies is, well, humorous on a whole 'nother level. So, thanks.
I do think that the nature of landscape photography is worth talking about. The
very definition of what a landscape photographic should entail is quite unsettling these days. Generally from an academic point of view, traditional landscapes of pretty places are considered uncreative and banal these days.
Personally, while I love to make pictures of pretty places, I find making a photo of a more ordinary but still vital place to be more satisfying. But that's not easy.
