Great work. I'm not convinced by the floating rocks though. It don't feel it works. It looks as if they should be giant boulders or rock formations tearing away... but they aren't. They're relatively small rocks which is telling me that it doesn't take a lot of force to lift them. Therefore I'm feeling that if the rocks are being affected in such a way, then more should be affected just the same. Maybe more smaller rocks/debris, the grass reaching in the same direction, the leaves of the tree, maybe even drops of water lifting off the river..
Just my humble opinion. Great work nonetheless. Thanks for sharing
