Beautiful image, Mark. I knew this challenge would play to your strengths, although I didn't recognize the location so I wasn't sure this was yours. Love everything about it. Congrats on the ribbon.
Lovely image. The trees are just a little "off", like they're artifacted in some way. Bothered by the amount of left corner vignette as well. Still really nice.
Beautiful composition,atmosphere and processing. My only nitpick is that I think the fisherman is a distraction. My eye goes right to them with all the leading lines and the way they(and the pole) cross the clouds it doesn't add anything. If they were in a "clear" spot with a good silhouette shape it could be a good addition. Anyway, great job and good luck.
