Great Long time Exposure, and -of course- a great Photo Added to my favs ----- The only critique i could give, is the one, that the Photo is unluckily cut at the Bottom edge. The reflections of the Castle Round Corner Tower are not 100% on the Photo. Anything else seems perfect to me.
Besides of the poor Quality of the Vignetting. All the Shadows look ok, only the Vignetting an the corners is pixelated (maybe its the work of the JPG Compression ?)
