Truthfully nice effort but I personally do not like the placement of the rocks. Try to look up on the golden ration of placement & depth creation(Amano & many other hobbists did talk alot about these). So it looks more "comfortable" to the eye.
Do spread the moss & tie them up with lesser on the top because overtime they will cluster more on the top of your rocks due to higher light available(that or algue will do the job instead).
Your tank looks small 1ft cube? Can try with boraras species(quite common) & small corydoras like pygmaeus, hastatus etc. Nice badis badis btw
Did you cycle your tank 1st?
