I have noticed that if you cut their access to the 'Net, people tend to exhibit high levels of creativity :)

You managed a good deal of details for the dimensions, while still keeping to the minimalistic approach! And that's a good thing :D

Good job. I really enjoyed this.

I really liked this one. I agree with ZeroSum, it reminds me the first Silent Hill intro :)

This reminds me of Silent Hill. Not sure why ;p

I find this a highly successful piece.

Yeah, you're right. Thanks again.

It does!

The arch is very thin now, it should be thickest at the ends; and it needs smoother AA esp on top.

 Thanks for the help. Hopefully it looks much better now. I suppose this is what I get for not looking at any references.

The bridge shape is wrong in several respects.

The arch curve could be more graceful, with either even curvature or slightly stronger at the top; with the arch ends either reaching deck level at the deck edges, or going down to the ground below the deck level (nicer).

The deck is too thick, as well as the connecting beams.

Nice dusk atmosphere, the car lights could reflect a bit off the nearest beam or two.

The sides are too random (both landscape and sky); suggesting silhouettes of trees or rocks or whatever could make it better.
