It took me a while to see the bug. I first thought the flower was "so close to the top" of the image. I like the flower against the background sky. That's a perfectly colored sepia sky.
Very out-of-the-box. This is not what I consider a sepia image, but I admit I can see an "overall sepia tone" and I think it is very "effective", so I am expanding my concept of this challenge. :) Beautiful image!
