I really like the first, super angle and I especially like the long shadow that sort of disects the railway line
I'd be interested to see whether cropping a little from the left hand side, to put the vanishing point right in the top left corner, would make it even better?
For the second, the straightness and the beautiful vanishing point effect make me think I'd prefer to see the tracks centred in the frame. Lovely combination of the autumn colours and the rusty tracks, too :thumbup:
On the other hand... don't hang around too long on railway tracks :shock:
