Bro... you should be submitting this stuff to magazines to get PAID! Seriously.
Magazines would want you to use your own photos, not someone elses if you are reffering to the original post.
Those photos are awesome examples of the principals of aquascaping. The actual underwater Australian pic is very cool. I have seen several others like that which look like an Amano tank. To me that is truly fascinating. It would be nice to have more American aquascapers, even in our own AGA contest. Jason Baliban has been the most notable. There has to be more out there, somewhere.
How about discussing the basic design models:
Concave, Convex, Mound, and Triangle. Which do you prefer, which is easier, and how do you add your own uniqueness to any of them since they have all been done a million times?
