Don't worry about conforming to anything.
Once we know what you're after we can help (we hope) to get you there sooner.
One question might be if you want it to scale. The reason we suggested you reduce the size of the rocks is so they aren't so overwhelming. It can make the tank seem larger than it really is if you have a half or quarter scale in mind. That's why you also see lots of tanks using tiny fish ... just so the perspective feels larger.
The reason we suggested various sizes of rocks is so that it looks more natural. All the stones I remember seemed to be the same size and stacked, but is that the way you would find them in nature?
When we talk about the fore, mid, back grounds we are merely thinking of the perspective. If this were dutch it would all be very regimented, but if you can define how they work in your vision, you'll find the tank flows better and draws the eye where you want it to go. If you were to put all stems in the front, it might be natural but it would also block the rest of the tank from view.
Like the stream you are trying to reflect you want the aquascape to flow from top to bottom, from left to right. When you look at a stream from distance, don't you always find yourself looking back up to where it starts and then back down to where it ends? James Hoftiezer
