How big is the pond? The biofilter looks way undersize. Just by the water flow it looks like 1000-1200gph pump. Why didnt you continue using round stone under the falls to give it a more natural look. Edges are nicely postion but then you go and put flatstone between, it looks choppy. Your mix of stone and plants look great its just the waterfall itself. Great job over all though for first attempt.
