I think you have captured the serenity very well, but if I was being hyper critical the wood coming out of the water perhaps wouldn't be so distracting if there wasn't so much sky in the reflection.
If I find within my self a desire that nothing in this world can satify, the only logical explanation is I was made for a different world. - C.S. Lewis
Wow, on closer inspection, there are a lot of logs under the water! My critique would be to focus on that just a bit more along with the reflection of the sky and oh boy, you got a great work on your hands! Thanks for sharing.
I like the reflection, but I too think that there is a bit too much of the water reflecting and not enough sky showing. Also, its good to make sure the horizon line...here the water line, is straight.I do like how well you captured the clouds...If you cropped the photo just below where that log is sticking out, then the pretty clouds would show above the lake, instead of in it....just a suggestion tho...Verena
