i posted a pic that has been up before. i did some work to it to darken it up. do you think its too dark this way? take a look and post your comments. it's the one with a sunrise and a guy walking with a board
In addition to what I posted under your photo, you might want to tweak the exposure a tad with a little dodging and burning to optimize your result. Just be sure to save each variation under a slightly different name so you can maintain the original source photo.
