Juvenile Chiffchaff (I think)

A number of the fine details such as tail shape, leg colour, and breast colour point to it being a juvenile Chiffchaff, LBJ's are tricky to i.d. in my opinion.
Anyway I had a good walk in and around a local nature reserve, it was very cold in the wind, but the sun was very pleasant.
Three Buzzards were gaining plenty of height, and a hare put a lot of distance between itself and my camera.
I have treated a lone tree to an antique look in extras, plus one of the Buzzards.
