I have to say, after reading all the books on design: landscape, photo, flower arrangement, architecture, etc. they all say pretty much the same thing as far as elements and principles of design go. Sure, some of the elements/principles are called something else and/or are combined together - they are the same. I'm not sure what design school my critiques went to, but I stand by my research. I do admit that it could be much better written. Look to see a better article on friday.
