#1 is pretty nice, but there's just enough brightness in the scene for me, but I still like it.
#2, as mentioned, is just too dull. The scene itself is nice, and I'd love to see a similar composition with more color. Make sure to get some good colors in the spring.
#3 has an absolutely gorgeous sky, but if you get past the sky, it's just a picture of a lightpost. It's important for shots showing how beautiful a sky is to also have some other interesting subject involved, and to me personally, a lightpost isn't that interesting, sorry. But yes, that sky is damn fine.
