The basic layout looks good. Perhaps some anubias on the big driftwood and put the grassy plant that's spread out in the middle back of the tank in a tighter clump directly behind the big driftwood. Other than that I'd let it fill in for a while and see how it shapes up.
I really like to right, no so fond of the left. May be move the wood and add a little more hard scape. Or move the wood to the far left and a mid ground. I might even try a smaller piece of wood. What kind of look are you going for?
