Jökulsárlón

I like the sweeping lines in the clouds that radiate to the corners.  You captured some beautiful light as well.  

The larger version is beautiful. Love the mix of cool and warm tones. I also like your choice of placing the horizon line to accentuate the clouds.

Alberto,

What I love most about this is how you've taken a bold subject like the glacial icebergs with the blue core... and made them just a contributing element to a much larger scene. ie. as Dave points out with the horizon line giving more emphasis to the clouds, and frankly, the reflection too.  Beautifully crafted.  The large view is awesome. In fact I didn't really notice the sun until I opened up the larger view. ;-)

The only small nit/suggestion I have are the whites above the horizon.  They look a little blown which would make sense if the sun was setting/rising in the middle, but it's way off to the left so I would expect such brightness there.  Minor though.  The colors and processing are great throughout.

The large version is a real treat, Alberto. It showcases the blue ice rather nicely along with the sun star and those sweeping clouds. The reflection in the water is a nice touch also. Beautifully done.

Beautiful, Alberto. No suggestions from, really like it as is. 

This is nice.  Ice, especially with some dark spots in it, can be difficult to photograph, and this is really lovely.  Great job on the sky and the water, too.  The clouds and their reflections really add to the lovely color of the ice.  Nice one.
