Not to bad

The riccia definately needs a trim as it is creating way to strong of a element. Distracting as it is right now. I would try grouping your plants a little more...Make one stand of Rotala(or one on each side if thats what you want but don't make them semetrical in size/shape). I like what is starting to happen in th emidground with the Hemianthus micranthemoides. Maybe try letting it fillint he dark spot under the middle riccia element and have the HM taper out and into the forground on the sides. Get rid of that single stem of Bacopa(or is it Ludwigia repens?), move it back with the others in the back left corner. Its hard to see what is happening with the background but maybe try having the Bacopa or Ratala wallachi?(I think) occupy a space in the very back, between the R indica and the Riccia. Either plant will make a good contrast in texture with the indica but I would probably loose the Bacopa/Ludwigia.
As for the staghorn algae. It shoudl go away as the tank matures if you maintain proper CO2 and Nutrient levels. Trun up the CO2 to 30-35ppm and maybe try a dos eof 2H20 or Excel to weaken the staghorn faster. A search/post in the alga forum should help you there.
