That looks amazing and would really be insane with a river theme background. I don't know if you are planning to but a root system background or even planting some mangroves in one corner giving it a look as if it is flowing out of a lake in to a river.
When I mentioned using a epoxy resin it would involve zero concrete. Just Make the shape you want out of whatever you feel the most comfortable forming then using epoxy to make a piece. You end up with just the epoxy to be silicone in and makes a great way to make caves and places to hide powerheads and what not.
