I too agree with preferring a pair (not more) of opaline gouramis, and skip on the dwarfs, particularly the highly inbreed (and weak) color variants. Floating plants would be loved by the gouramis and will incorporate them into their nesting behavior.
I like the look of your tank, and very nice crispy Java fern and wood.
A couple of suggestions - If you place the heater vertically on a corner it would be less conspicuous and look nicer; you have sufficient water circulation for that not to be an issue. Finally, your tank's contents would jump alive if you attach black construction paper to the back of your tank, also hiding filters and cords. Good luck!
