So I went back, to try and get a better shot (as always). But kicking myself I left before the peak of the sunset everyone is now posting on Facebook. In my defence, it's not what I was going for. I prefer the light when the sun is still just above the horizon, though you don't quite get the same colours. Only 5 mins from home, so plenty of time to have more shots at it.
