Just uploaded this on PJ and I'm no longer working on it. But I just wanted to say thanks a lot to everyone who helped. It makes a huge difference for my learning curve.
@PsylentKnight: I'm doing a series of nine 300x100 landscapes, and I already had plans to do another piece like you describe. A road from the foreground to the background. So I like the way you think, but I'm not using it for this piece, otherwise they'll look too similar
@Friend: I'm really digging what you did with the light rays. Maybe not for this particular piece, because it makes the air look as thick as water. But it's definitely something to keep in mind for pictures with lots of particles or moisture in the air. I have another piece in mind specifically, so I will use your idea later. I'm glad you had fun, it's always very interesting to see other people provide a completely new take on one's own work.
