There are a few things to point out in this picture, first thing, depth of field, this picture makes the mushroom the main focus, whilst the background is blurred. Also, we can see the texture inside of the mushroom. I like this picture the most it is zoomed in, and the texture is smooth.
Grand Kremlin Palace, Moscow, Russia, breathtaking as all of them are in Russia! The Grand Kremlin Palace was built on orders from Tsar Nicholas I in the mid-19th Century. The architects outdid themselves!
