This does not meet the challenge description, as it is not a landscape. As for the image itself, you may want to sharpen the image a bit more after down sizing for the challenge. . Most people use Unsharp Mask to bring back the sharpness lost because of down sizing.
This picture does not fit the challenge's theme.. It is supposed to be a landscape picture (taken or cropped in portriat orientation).. Nice picture though!
Vertiginous. The odd angle makes this difficult to look at, but also strangely appealling. I think it helps separate the subject from the background landscape, which, by the way, is not the subject of the composition, so I'm struggling to see how this fits the challenge. Perhaps you should have taken a horizontal crop and entered it in the other challenge.
Does not meet either challenge. This is a portrait in portrait orientation. Its not a bad photo though. This man looks interesting.... someone I might want to listen to. I'm sure he has some very interesting stories.
