Patterns and muted tones make it for me. Not sure whether gentle increase in contrast would have added further to emphasize the patterns. Thanks for sharing Adithya..
"Calm", "Peace" words that came to my mind when I saw this image. Liked the way it is. Simple and beautiful. Coincidently, I also made similar image last weekend.
Thanks every one for the inputs. @Ganesh, I have tried to increase the contrast but felt that was taking away the over all feel of the image. Hence sticked to this one.
