Idk...I think that is stretching it. If she had been standing and the waterfall was clearly the shot then yes I would agree. But you don't see the waterfall, it's not view-able unless you run all the way to the other side of the bridge and down a hill to actually see it's even a waterfall.

I mean honestly there are 'waterfalls' of some sort in rivers everywhere in real life, so if this was a real picture you could say 'nope that river has a waterfall a mile up so it's against the rules.

Ok, the above is over exaggerating... lol but when I think 'no waterfalls' I think a waterfall that is clearly within view and is clearly a waterfall. I didn't even know that was a waterfall there until you ran all the way over and down the hill to show it, thought it was a bend in the river to be honest lol.
