If I were you, I'd try to create a riccia carpet all around the driftwood. The anubias should look nice when it grows out. try moving it to the left. And play around with your driftwood, slanting it at different angles and what not. I think it takes up a lot of surface area, and I feel it'd look better if it was vertical. Also, the thing with smaller tanks is finding plants that don't outgrow it, and too many plants simply make the tank look crowded. Too little, and algae has the upper hand. And I'd lose the java fern, I think it would grow too big for it. HTH, and good luck!
