I cant be 100% sure, but it looks like you were there in Mid-Day, with straight overhead light (Looking at your shadows) Cruisertoy. One of the main reasons your image doesn't look like Clark's is his looks like it was either shot in very early morning, or very late afternoon, and almost looks like it was an overcast day or at least had some good cloud cover
Makes a lot of difference in the look. Plus, with a long exposure to smooth out the water like Clark did, it'll pick up more of the blues in the water due to it being exposed for a longer period of time
Great shot Clark!!
