I think you would achieve a better look, and balance, by removing the tall tree-like dw pieces from the center of the tank, and place them in the rear left hand corner. The 2 white rocks there might be better placed somewhere slightly off-centre in the middle right (or middle left) portion of the tank.
You could then consider adding your intended lace rock in/around that area to create an attractive rock pile construction.
The idea is to play with your set-up a little to create main tall focus points at both ends of the tank, and a lower center area. This might entail re-locating some plants to get the look you want.
Your preference of course, to see what appeals to you most.
