This is a little to far out there for me.If you could have cropped out the bright sky maybe this would have improved the comp.The color, given the scene, is good.The light on the subject pond with the grasses up front looks fine and could make for a good photo.
probably not the best candidate for sepia, there are too many midtones and not enough contrast in shapes. Also, there is no real subject for the pic and it's not framed on anything.
