Right, sorry for the delay in providing feedback on this – took me a while to find the image and to add it to the post.
This is an image you should be proud of. When creating landscape images I tell people to look for foreground, midground and background – you have managed to achieve that with the snow, lake and mountains. Not only that the use of a reflection to draw attention to the mountains has really worked.
Because the image is small I can’t comment on whether it is suffering from any blurring due to the motion of the train – hopefully not. Even if it is – at screen resolution it is not noticeable.
If I had to nit-pick (and this really is minor) the only thing I would change is to clone out the slightly blurred fence post at the very bottom of the frame.
Other than that it is an excellent shot – well done.
