Sepia is a good choice here, but the image correction resulting blotchy patches of focused and unfocused areas did not work for me. In my opinion it would have been better if that had not been done.
Wow, what a dramatic backdrop. I love the clouds and the mountains rising up gently. The deep landscape really brings for the feeling of alone and solitude, though the child is a bit soft focused - would rather the focus was much sharper on him/her. Nice use of sepia, though I'm wondering if it would be better as a b&w. Use of natural light is good as well. Nice job. 7
Shame about the pixelation here, it is a good composition, taken from a good view point (angle). What resolution is your camera and what post processing have you done?
Make your subject just a little closer and maybe down on the page a little. Cute shot of a cute child, let's see him just a little better. Otherwise, beautiful landscape shot, colors, tones and composition.
Personally I feel that this image could have been stronger if you were closer to the child. Then the child would have made a better impact yet you could still have all of the scenery in the background.
