Looks like you are off to a good start Roy. Personally I like the last pic hte best but agree that there needs to be work done to the rocks. One issue I have wiht rick, especially in small scapes, is that a) one looses alot of planting area and b) its hard to find nicely proportioned rocks that are intresting rather than blocky, or perfectly round. THe back 2 rocks seem ok to me but It would be nice if th 2 larger ones int he front were taken down a bit. They are just a little to big and to blocky for me. They seperate the front from the back to much. Placing them like they are and then adding the substrate might help as it would bury the bottoms, making them look like they were rising out of the earth, rather than sitting on it. I have been searching for somehting like the Dragonstone, or even black lava rock for some time now with no luck

Maybe you can help me there?
What kind of tank are you going for? That layout looks like a prime target for an Anubias, microsorium layout. Consider using Marsilea for the foreground, if you go with one, as it will make your life TONS easier. I would love to see a nice red plant in the backleft, subtle rust red color though.....anyway, its your tank so have fun! Keep updating us.
