I like these alot Riaan;
Where I am in Florida, there is not too much opportunity for Landscape work (no mountains, no rocks), so I am pretty bankrupt in the "landscape photo" department. In fact, so far I have taken only one truly satisfying landscape shot (to me).
Interestingly, my girlfriend almost always takes her shots in portrait mode, as you and Mike do, whereas I almost always take mine in "landscape" mode. I think you have made excellent use of the portrait perspective in your images, Riaan, and you have inspired me to try to take more such shots myself. (Oh, how I sometimes wish I were back in California again so that I could make better use of my super-wide lens on the California beaches ... rather than the comparatively mundane beaches here in Florida!)
Anyway, sorry for the digression, but I really do like your photos.
