Wow, all ADA stuff? You some kinda richy rich or something? LOL
Don't mind me it's just jealousy, my CO2 reactor was an old gallon jug of Hawiian Punch with an air hose coming out of it and going into the input of my empty power filter. I had a bunch of tanks setup like that back in the mid-late 1990s.

Try to decide what you are going for, if you're going for Amano style try to remake a landscape photo using aquatic plants, wood and rocks cos that's generally what he tends to strive for is an impression of a scenic landscape. Whereas the Dutch are more precise with their plant placement trying to create a visually pleasing "aquatic plant garden" while strictly adhering to the rule of thirds and golden ratio.
