Looks good George.
Glad you'v moved some of your hair grass. The idea of of planting hair grss around rocks or wood is to give a sense of age, showing that the plants have had to grow around the age old stones.
Great ideas with the lights, not many people bother doing fancy lighting affects. Iv done similar things with my SHAKKEI nano and have a similar plan with my SOAR nano.
The other technique will be to add a fan or hair dryer, to blow a ripple on the water surface,that looks dam good when combined with great photography, back lighting and nice aquascape. I think its not just the aquascape thats important its how you present it, an avarage design can look more than avarage with a little creative photography, it adds to the fantasy of being in another world.
I like you scape George,the only thin I would say is the topography of your substrate, id like to see more of an incline to the rear of the design.
