Hello Joy. Congratulations on finding such an excellent subject for the symmetry challenge. The composition is very good, especially with the flagpole being exactly in the middle. The reflections are amazing. The green of the hedge breaks the blue/white color harmoniously. Good job!
A couple of things I'd change would be that the whole image seems to be tilted to the left. A slight rotation in the post processing would have fixed this or maybe holding the camera more level when taking the shot would have helped. Also I would have cropped out the sidewalk, it is a little distracting.
I don't think the image is too bright as has been mentioned in the comments below, but maybe the saturation could have been tweaked to bring out the colors more.
All in all this is a fantastic image and you can be proud of it.
A little bright. Maybe the contrast could be turned up a bit or the brightness down, or some combination of the two. Great Symmetry. Very nice image - 9
Beautiful symmetry here! I especially like the symmetrical reflections of each wing of the building back into itself. Sky seems a bit washed out, but overall, very nicely done!
