For a first attempt, you did an excellent job.
I'm not a fan of the Moss Balls, either. However, one placed inconspicuously on the left would not look too out of place, I don't think.
As for a background plant, I don't think you'd need one. The open space accentuates the forward-pointing nature of the left-hand driftwood piece and I feel that background foliage might dilute this effect. As is, you have a nice V-shape going and rather than add plants, simply focus on the fine-tuning (i.e. manicuring) of the plants you currently have. If you put anything, just some stems placed sparingly in the far back left and right corners to provoke the image that the tank is wider than it really is.
