I like your tank , there many possibility to make a super tank in there
Just a few advices :
Divide your HC by 4 or more , it grows faster.
Make a midground and a foreground (i can see HC in background and blyxa in foreground)
Maybe you should try to put your driftwood in diagonal cuz the echinodorus will hide the java moss and this can give another good style.
But its just my opinion and its your tank.
