I think this is superb focus and composition! Love the color and I happen to think that dandelions are really pretty - great job, good luck in the challenge! high score:)
Choice macro. The lighting is a little uneven, the lower part of the flower appears a tad too dark. There probably wasn't too much you could have done about that though. Otherwise a very good pic.
One quality to these macro shots that sets others apart as "outstanding" from just "good" is their uniform lighting and their solid backgrounds. Here there are some "hot spots" that are distracting and the overall exposure seems low which is preventing some of the details and color from standing out.
Very clear and nice... excellent macro... truly wonderful. Nice job! I didn't know that dandelions were that pretty! Hey did you rub it on your chin?? :-) I wish you would have gotten the tips in of the flower, but it's not that big of a deal. -8-
