I'm not very big on photography vocabulary but here's my best shot. That last line could've totally been a pun, but I'll leave it at that. LOL!
My initial thoughts were 'This is a good photo.' The three rocks are focused very well and you can tell that it's the 'center piece' of what you wanted to showcase. Compositionally, it's great. You can also see the detail of moss and other vegetation is growing around the rocks. It's definately something that I can see in a science textbook or maybe a computer desktop.
As far as it looking relaxing. I'll be totally honest when I say it's not what I felt initially. I get transported back to the 7th grade reading my biology texts. To me it's just a picture of rocks. A good picture, but still a picture with rocks. I hope this next paragraph will make sense.
I'm not a photographer but a choreographer. In a lot of ways, we're working in the same way and run into the same problem it seems. You only think about what the audience will be seeing in front of them. For me it's the dancers on stage. I think about the audiences point of view and what I want them to see. It can make for a very boring, flat, and two dimensional work even though the choreography is dynamic.
A good fix for this will be that I have my dancers run the piece but I stand in different spots in the room and watch. I'll have them perform it with their backs to me, slowed down, sped up, retrograded, etc. Sometimes (A lot of the time), the composition totally changes and makes for much more interesting, abstract, more dynamic scene. I guess what I'm trying to say is try to find a different angle or perspective to take your photo. Maybe get in water and shoot from up close, further away, left of center, over it, under it, any which way instead of straight on. Maybe you don't want to get all three rocks. Try instead taking a picture on the side of it and maybe just barely getting that rock thats furthest away. just work different angles until you capture that essense of feeling you wanted.
Also, lighting totally helps with capturing a mood. This is why people turn the lights lower at fancy restaurants at night and all those crazy flashing lights at discos. I'm taking you wanted a soothing feeling. Maybe try black and white, sepia, making the tempertaure a little warmer or cooler. Try it out. Hope this helps!
Again, good photo. Keep it up!
OMG AND THAT FROG PICTURE TOTALLY SCARED THE SHIT OUT OF ME! I HATE FROGS!
