Really like the reflections in the last pic - well balanced, and like the disappearing point of view
Well done.
As for the other two -
I see what you're trying to get with the goalpost one, and it
almost works for me. Not sure about it though. Perhaps try a crop with less of the black foreground, and maybe a little less of the tree on the right.
The bridge is a classic shot which I think would be helped by desaturating the colour (I don't think a full black and white is necessary to make it work). I love the way it just disappears
into the fog (or is it the way it appears
from the fog?)
