Nice!Yeah, I agree with you but didn't had my ND w/ me Actually I didn't have anything else than camera with me at that evening, just took it with me when I left to outside to take fresh air, walk and relax.
Would've looked really great with a longer exposure.
I really like the composition and colors!It could have been bit sharper at trees but EF-S 17-55 ain't the sharpest lens out there. But the main subject was sunset and cast from the sun to that rock.
I personally think the image could be a bit sharper, but I still like it very much.
