Blinky,
Glad to see you kept the groups larger than a few plants.
That's a good sign in design.
I am really picky about my hard scapes, the wood, rock gravel.
A great deal of time should be given to this.
I spent several months haggling over one design.
I'm still not happy with it either
Also, consider looking at the AGA's ADA's and ADG's designs and see what appeals to your sense of aesthetic.
I have never been one to judge others much, I just don't like it because they cannot get inside my head and I cannot do the same for them.
I think if the tank achieves your goal is the key.
Take your time, you have plenty, pick any new plant very carefully.
Realize also that you can switch a plant out and add another one easily as time goes on.
You can also search the Stages of the Aquatic Gardener on the APD for some other ideas.
Honestly, you are coming along quite well.
Areas I would suggest you play with and explore later:
The wood placement. After a big cleaning, you might decide to place most of the wood upward in the rear corner, an asymmetrical design.
Add moss to the wood.
Replace the Hygro with L aromatica(will add some purple and color).
Replace the java fern with a narrow leaf variety.
Add more Crypts along the bottom, consider dwarf Lobelia in place of them.
Add a cork backing to a piece of glass and use this for a moss background instead of plain glass.
Paint the back of the tank with acrylic latex black paint.
Do not run out and do these things, take your time, think about them, see how you feel about them and try them out.
