Paint Practice Sahlt

The water splashing effect is really good, has a nice dynamic to it. Though my eye is drawn most to the buckets she is holding. Simple, yet very effective lines.
There are some horizontal lines, that I don't understand, though. But maybe there is something behind the water fall, that is causing those. More stone like the one that is already breaking through the water on the left. The one that she is eyeing so carefully. Wouldn't that rock take a lot of the force (like you implied with the "waterless"/shaded parts beneath it), so she would be kinda cheating?
