Those are amazing! You'd never know they weren't real.
On a side note: wood that is in water will last decades. I've often questioned that myself when I see pros using wood in a waterfall or for a stream drop, but I saw a video of a pondless waterfall rebuild just recently where they pulled a log out that they had used in the original waterfall. It was as solid as the day the put it in.
it wouldn't last long with water always pouring through.
