The whole photo has a slightly grainy feel to it. I think the easiest place to see this is the under surface of the wings. As an aside, though there is no clear reference, the photo has the feel of needing some clockwise rotation for it to look level.
It is certainly a very nice picture - where exactly is it taken?
P.S. Matt posted at the same time and beat me to it
. Hi there Matt!
P.P.S. As I 'P.S.'d' you posted too Mark. I would not appeal - I am confident that the Head screeners will see it as grainy too, and I would also agree with the slightly oversharpened diagnosis.
P(x 3). S. We are all posting at the same time! I figured it must be either Scotland or the Lakes. I don't know Scotland, but certainly could not place it anywhere within the Lakes - but the environment looks very similar.
