Is that wood or rock? It's kind of hard to tell.
As for the scape, yes, it does suffer from an overdose of symmetry. One suggestion would be to remove one of the rocks/pieces of wood. I'd suggest the one on the right, then move the one on the left a bit more toward center. One of the good scaping techniques is to create an optical center about 1/3 of the way in from the left side.
Another possibility would be to create a "slanted trail." I'm using parentheses around that because there's another name that I can't remember at the moment. Basically, you want to create two diagonal, non-perpendicular lines that intersect behind the tank. One line would begin just behind the front left corner and meet the back wall of the tank about a third of the way in from the right. The other would start near the right front corner and meet the back wall a few inches to the right of the other line. Hence they would actually intersect behind the tank. These lines could be created with plants, driftwood, rocks, etc. And they don't have to be unbroken lines. In between the lines you'd want mostly empty space.
In the case of your particular tank, move the right driftwood/rock a bit further right to create one line. Then one on the left would probably just have to rotated a bit to create part of the second line. And then you'd want to move that large Anubias(?) that's smack in the middle. Keep the large plants behind the two lines, and either leave the middle empty or plant foreground plants in it. The idea is to create a slanted trail going off into the distance, which helps to give the illusion of depth.
That's probably a pretty hard-to-follow explanation, but these are two of the easiest to create aquascaping techniques.
