I like this and agree withy Marcin about cropping but not quite as heavily as I feel the run off area of water is necessary to balance this picture's peaceful feel. I'd go about halfway between the two and then it's lovely
It's definitely the HDR factor causing probs with EXIF but it might also be the Canon factor as for some reason, and I think this was flagged up by Steve ages ago, Canon EXIF and Pixalo doesn't quite mix for some reason. i have no idea why, I just seem to recall either Steve or Dave mentioning it way back.
Lovely pic Fi, well done.
Cheers,
Rob
