Compositionally, I really like this shot. You "fill the frame" but still leave a bit of black in one corner and this seems to balance the shot very well. I also like that you chose to photograph the back of the flower. The only teeny tiny nitpick I would have is that I think the shot would have a bit more dynamics if it were tilted ever so slightly to the right so that the stem was more in the corner. However, please realize that this is probably just a personal bias of mine as I really like tilting shots. :)
Technically, you have nailed the exposure, focus, etc. The lighting really accentuates the details, and the flower really does look like a miniature sun.
Overall, very well done and congrats on your top10!
Wow! This is mind blowingly good! The composition. The detail and texture. The vibrant colors. An excellent choice for a spot on the front page in this amazing challenge.
wow, what a sharp, clear and bright image. So realistic, you can almost touch the fuzz. I like these flowers from behind (I know, sounds crazy). The black background is great, but the border could have been a bit thinner as to synchronize it with the delicacy of the fuzz.
It's nice to be shown the other side of things from time to time. It's also a dangerous way to go, but you mastered it with a fantastic composition! 10
