This is a lovely picture but very dark. I think the reason is because of the profile you have used Sue. Your picture is saved in Adobe RGB (1998) profile but when this is shown on the internet, it will invariably look darker than it does on your computer. You need to convert it to sRGB IEC 69166 profile so that it will show correctly on here.
I have done it for you (and made a slight adjustment to lift the contrast) to show what I mean.
Cheers,
