At the Shore

I wouldn't suggest having the rocks any sharper, personally i think that since everything else in the picture is a tad blurry, it would be better to have them the way they are. The water as well, I think it would look really complete if the water wasn't drawn as sharp as everything else seems rounded and soft. My attention goes straight to the water splashes, maybe that was your intention but it takes away from the rest of the picture and forces the attention on to one spot. 
Besides the water everything else is very soft and creates a kind of a comforting/cozy feeling for the viewer. I really like it. Especially loving the snow flakes that are smudged which looks like they were caught in movement. Overall an amazing piece, really loving it!
