Sorry to see your apparent displeasure from the lack of response to your thread. You may have had more feedback if you gave us some more information about your set-up. Anyway I'll give my humble opinions/advice - hopefully it will help.
The "lush" look you describe is a result of a high density of plants, more than just a case of simply re-aquascaping what you already have.
You don't mention lighting, CO2, substrate or ferts used. So I'll assume you have 20W with no CO2 and a plain gravel substrate.
With this assumption you will acheive better, faster results by upping your lighting to 30W minimum and injecting CO2. I've recently posted a method of simple, cheap DIY CO2.

The substrates described in this same post will help too.
In summary a good-looking planted tank is a result of acheiving the right combination of lighting, nutrients (CO2, ferts, substrate) and plants. Once you have the correct hardware you can then concentrate on the aquascaping.
Simple aquascaping techniques -
Choose an overall style i.e. a U-shaped compostion where there are tall plants left and right, shorter plants in the centre. A triangular shape where the compostion slopes from one end to the other or a mound-shape where the centre is full and the outer is empty or short.
Design the layout around a main focal point i.e. piece of bogwood. Decorate bogwood etc. with ferns or moss for a more "natural" feel.
Plant like stem plants in groups. Plant each stem seperately and don't use lead weights, use tweezers to fully plant stem. Use lots of the same plant to create a lusher look. Use easy, fast-growers i.e. Ludwigia, Hygrophila species to acheive quick space filling.
Foreground is very important. Sagittaria natans is a good plant that carpets easily and is undemanding. There are more but because foreground plants are short, less light reaches them. They therefore require higher light levels. And Higher light = CO2 injection.
