No 3 is the strongest image imho - so I'll talk about that one. I like the colours and light it has a very serene feel to it. Your northern skies and low sun give such magical shots. I like the compo with the bridge wires mirroring the shape of the snow in the foreground and the uprights doing the same for the trees. I find the tree on the right to be a distraction from this and if I were to want to improve the image I would crop it in from the right to where the bridge wires meet the trees.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
