looks like healthy growth.. as far as suggestions.. try and arrange the plants by background/midground/foreground.. I know this is very hard for a 5.5g since almost all plants will overgrow it.. but perhaps once you get the co2 straight look into regular midground plants to use as background for this tank since those wont outgrow it in a week. Maybe HM as background, crypts as mid and the riccia or another carpet plant as foreground. Another random suggestion is for this size tank try and narrow down on plant species.
