Thanks for all the constructive comments. I agree that the blade of grass at the bottom right is in the way, but I wanted it there to emphasize the relationships in the picture: blade of grass>dandilion>tree>jet trail. Again thanks for all the comments.
Nice focus. I think the photo would have more balance if the right side was cropped where the out of focus leaves are. The photo would probably end up as a 480x640 instead of 640x480 but it would have a little more impact. Overall, great job.
What great focus you have in this picture! That dandelion is the focal point, and appropriately, it is in great great focus, while everything else has a nice blur to it. That's great use of manual focus, and not a lot of people seem to be as good at it, which is why I have to bring it up :) Nice framing, though I would have waited for the airplane trail to dissolve, if I could have, as it is somewhat distracting (on the minor, nitpicky level). Good shot, and one that I am sure will be among the top contenders this week.
OK, this photo breaks all the rules of compositon yet somehow it works very well. I think it's the nearly horizontal line of the contrail in the sky that brings my eye back into to picture and keeps me looking at the subject. Bravo on an unusually terrific composition.
