First, let me preface this by telling you that this is my first official critique. Please bear with me as I learn.
I really like this photo. I think it's a very strong image and the symmetry is great. I'm not one who thinks that a mirror image is necessarily the perfect form of symmetry, rather that the photo should have a balanced look. I think this photo achieves that balance.
Like others have said, the tree at the bottom is distracting and cropping it out would have made the photo stronger. That's really the only thing I can see that I would change.
The colors are nice...pretty blue sky, white clouds without being blown out...good focus and interesting perspective.
All in all, I think this is a very good shot and most impressive for your first submission!
Good luck with future challenges and keep up the good work!
Immeadately brings to mind another set of "twin towers". Seems to be a little off balance and the bottom part of frame should have the leaves cropped. No the less,this is powerful image.
