Thanks for the replies everyone.
Sorry I haven't had much of an internet connection the last few days so I am a bit slow to get back to anyone.
I am at least glad that the photo has stirred a bit of discussion
I definitely agree about the wall Slobodan, thanks for that piece of advice.
In terms of colour/saturation... I am glad that for your comment Paulo; because I do believe the colours suit the scene/suit the feeling I had while standing watching the clear sunset sky.
HOWEVER, I do also think that I have probably gone a bit over the top. Usually I would leave a shot for 24 hours then come back to it for final touches before I post it somewhere. Because I knew I would have limited internet I skipped that process for this shot. Re-looking at it I probably would have dialed it down a little bit (but not a huge amount). And I think that if I do print this shot I will take the saturation down a little for print.
Again, thanks everyone for your input. It is helpful to read.
