Different screens and how things will look is always a struggle - my picture is a good example of the problem. I tweaked various things because the spider in mine really was invisible originally and no one could see it. Even now people nearly miss it, hence the comment on this contest from munkees "When I first saw this photo, I did not even notice the spider, good capture."
If I'm truly honest with you - I think yours is a beautiful photo but I would tweak it a little, it looks a bit dark on my screen too.
