the green vs. mist in the background seem very well captured and the silhouettes in the fronts are not bad either but may be you should try different cropping or angle (and to park the car out of picture :)
Not a bad idea, but I think the foreground is too light to be a good silhouette and too dark to be a good illumination. The blown out sky is also a distraction. I think you could improve upon this shot by straightening the horizon, cropping more off the top, adding light to the foreground and contrast to outside.
I think it would be better if the focus were on the foregroun (the mother and daughter) rather then the background. I like how you've got the streaks of rain though.
Nice silhouette, but as it stands isn't very attractive to me. I think this shot has a lot of potential, however. Take away the car, straighten or remove the walls, and I think it would take on an entirely different feel.
The people looking out take up too much of the composition. If you had gotten further away and angled it more to the right I think, it might have made for a better composition.
The silhouetting works, casting a gloomy mood over the subjects. I find the sliver of a car to be a huge distraction though, and I wish the outside view is less washed out. 5
