Wow, that is sweeeet. Very difficult to offer any critique here. The image is crisp, the composition is wonderful and the visual impact is substatial. Exceptional.
I'd normally consider an image like number two to be too centered. However, with the strong vertical and horizontal lines I feel it works with a Mondrian style composition.
Love the first three, with the first image my fav. Crisp, engaging, vertiginous.Great variety of geometries.
Second works especially well because of the figure apparently suspended in the middle. What's going on there? Keeps me coming back.
To me, a good image must say something. It may be beautifully harmonious in proportion or jarringly harsh, but it shouldn't be dull. How do you explain what makes a good image? At best the "rules" are conventions that simplify discussion. They aren't art and they don't make something art. They may help make something interesting pleasing, but following rules won't make something dull interesting.
