Nice shots. I agree with reznap about a vertical comp for the 3rd. I think the post processing was a little heavy handed though. The first isn't too too bad, but the rest need the saturation backed off a big and maybe some of the shadows dodged a little. Could you post the originals unedited?
LOVE #1 That road seems like it goes forever!!
You're not too far from my home town (Elk Grove)!
I'm going to be transiting this road during my move from NY to CA, maybe I'll be so lucky to get some pics like this.
Love the first pic! EXIF says you shot it at 1/1000 and ISO500. Any reason you didn't set a slower shutter/ISO100?
