Composition - Well I see you're somewhere warmer than where I am. We just got rid of the last of our snow and have had milder temperatures for just a few days. Oh the critique, right. The composition of this photo is good. It isn't strong, or extraordinary, but there is nothing wrong with it. I like the background with this shallow DOF. There is a little color here and there to break up any monotony you might have. With the subject you chose, I think you did pretty well. The top flower looks like it might be a little washed out.
Technical - For a macro, its a little soft. I think that might be fixable with a sharpen or two. It might also be a result of the ISO set at 400. Color looks great. DOF is good and exposure is maybe just a touch too long. Nothing really out of place though.
Overall - The composition is good, but really lacks the "wow" factor. The photo is pretty well taken but I think I'd have set the ISO to 100 or less. Nothing about that picture is really wrong, but it doesn't have that little extra that'd make it stand apart from the rest. Hope that helps at least a little. Good luck on future challenges.
Looks like a constellation in the sky. Nice composition. The focus is on the fence and I would like it better either more focused or more blurred, this is just in the middle.
I love to take pictures like this one. In fact this looks very similar to some I took over the weekend. Overall I think you did a good job here. It might have been better if you had clipped off the one closed bud in the background and went for a little less DOF. The grass in the background is a tad distracting.
Beautifully taken and the background makes it clear that it was indeed taken from above.
(Not that I doubt that any of the flower images were taken from above, just that many of them don't make it visually clear within the image itself).
