Hi Peter I am not an expert on these things by any stretch of the imagination, however, I reckon it is brilliant.
I don't see what the other experts see, and just see something that is awesome for any human to capture.
Dont get me wrong, I loved imaging when I was doing it some time ago, and if i captured something like this i would be over the Moon so to speak.
So any small colour issue is not an issue for me
It is just amazing what we, well not me, but what you guys image and show us the end result.
Love it.
Leon
