You pictures are great! Very sharp, nice colours, great composition. But how do you succeed to create files, which have 551K (like this one), which is 10-times more than ours. You probably don't use any .jpg compression.
Since SP obviously doesn't have any problem with disk space, the only issue is a slow downloading, but some compression wouldn't harm the quality, I guess.
A very nice photo, but you should try removing some of the strong bluish tint. I did that myself on a copy I downloaded, and with the true Dolomite colour it becomes an even more striking picture!
