I like the concept, but the lighting is overexposed.

I see what you may have been trying to do by the angle, but I believe the top of the rail car should be parallel with the top of the frame, instead of being just off of parallel.

I like this one, except for the placement of the flower.
The water droplets are distracting on the wood just in front of the flower.
If you moved the flower to get the water droplets out of view, it would be a better shot.
