Your sun here is great! Nice reds and oranges.
But I like to see the setting sun in some sort of context usually. Like with mountains, or boats or something. You know, to give a sense of scale and overall beauty.
But that's just my 2 euro cents.
Later next week I will drive up to the peak district and try your advice meysha, I hope to get some nice sunset's with the mountain's and hills and the other nice stuff up there.
