The train is too small and does not dominate the shot. The detail of the trees has been lost too. A little under exposed. Shame about the fence in the foreground - it's a distraction.
This has all the ingredients for a great image but I feel it may have been missed. Such a shame you could not get up to that fence and shoot over it as it really does pose a barrier to this picture. Exposure is great but I feel we could do with seeing a little more of the train. This is an amazing setting and I think you could have made this good picture great.
