Aaahh! Opinions !! :-)

Thank you, tantarus!
Yes, it's blueish. /LOL/

aprilgem:
You're quite right and the only defence I've got for making this is I wanted it to stay within a colour scheme biased to blue. Exception - the drifting, empty life bouy in an opposite color.
On the other hand, it is originally ment for print and as such there is better tonal separation. Seems downscaling and jpeg-ing makes bad things ...
