What an odd little mushroom! I love the color, nice and vivid. Fits the challenge in general, don't really get a solitude or lonely feel from it. I think the focus is great and the use of natural light is too. Would prefer either a slightly skewed view or off-center instead smack dab in the middle, just for added depth and interest. Nicely done. 6
the DOF may be a tad shallow here. there's some action happening there in the backround with what looks like a lot of tree branches or something that is kind of distracting as well...
does not give the feeling of loneliness to me. Judging as a mushroom picture : Sharpness and color is fine, composition is bang in the middle. Should have cleaned the grass off the mushroom. Unattractive specimen.
DOF seems a touch too shallow here - fromt and back of the fungus are drifting out of focus without concentrating the eye on any particular feature that jumps out to me, especially with some of the grasses being within that plane. Odd composition too - perhaps a compromise between a broad context and a very close concentration on the subject.
I don't know if this was your intention, but that shroom almast has a human face to it. Not only that, but a sad, miserable, weather beaten face too. I LOVE IT!!! Nice use of depth of field. The only critique is that it is too centered.
