>>2846311An out of focus backside of a human being throws a stone in the water. Well!
That's what I figured out after looking at the image for about 15 seconds, which is quite a long time to look at an image and get what it's about.
Here's the deal: There's SO much empty space and background in this image.
You should have composed this in a way so that the splashes in the water are the center of attention and direct the viewer toward them. Instead, what takes the attention is the out of focus back of the guy throwing the stone, which is the point of greatest contrast. Then there's the HUGE lake of corse.
Compared to these two elements, the splashes in the water, which is what WOULD give the picture a dynamic element disappear in an uninteresting part of the frame, they are absoulutely TINY!
Go for a different framing and get everything in focus next time.
Think about what is important, how big you want it to be in the frame and what you want the viewer to see first.
You can use all kinds of compositional techniques to direct the viewer's eye, which is all a photographer has to do, besides finding interesting subjects.
