Hi Stuart,
As a kid growing up in New Zealand we always thought that Australia was a hot place to live. No one ever mentioned snow, frosts or cold winds that can take your breath away. Tourist brochures have a lot to answer for.
Now, this landscape is very attractive, and it is the sort of photograph that many readers probably wish they could have taken themselves. Like with most things though, it is the details that can let something like this down.
The one thing that I would like to see removed from the photograph is any hint of the foreground. To see those few scrubby bushes appearing in the bottom left and to the right of the frame simply distracts the eye away from everything else that is beautiful in this photograph.
If you clone out the bushes the photograph will look so much better; it will almost be like you are looking across to a magical island.
Then all you need to do is to crop a small portion of the sky and you have yourself a very beautiful panorama.
Well done... now go have a cuppa and warm yourself up!
