Yeh Gem's right about the 2nd shot there I think Casil.

The composition of the 1st shot is better in my opinion also. It does seem to be lacking some sharpness though.
Not sure what focal length you shot with here but I suspect you were testing your new zooms length. I'm guessing we are seeing camera shake for several reasons ... new lens so you aren't use to it (I have the same issue with new lenses) and perhaps the shutter speed was too low for the focal length you used. Judging by the waters blur you used a slow shutter for sure.
Maybe you were just shivering in those freezing temps

Is it an image stabilized lens? If not, then once you get over about 200mm or so (depends on the person) you are either going to need a tripod or a faster shutter speed than what you get away with at shorter focal lengths. Frankly even an image stabilized lens only gets you so far before needing the tripod or faster speeds.

Your exposure is quite good though in that first shot too.
