Rust....now that is a good title for a contest. Yes, and why not it is metal. I like the grunge effect and your considered composition shows you took a photo and not snapped a picture. Nice that you got all the nails in also.

Yes, you managed to capture that pop out of green of leaves, however, can you see the large amount of bluish hues inbetween the green? Your sharpness is on the green and that catches our eye. Filling the frame was the way to go.

Not a lot of interaction between these two characters: the woman looks at her pictures on her camera! it's a shame because the backlight was rather well managed.

You may have a slight tilt to the right on this one. I like it for the interest factor.
