I quite like the second one personally. I like the spartan zen nature of it. There's a level of equity in it, between the water, and the rocks, and the fluidity of the water as it swells around them.
The toning is quite nice too... Oddly warm, against the 'cold' of the snow.
The first image doesn't really do it for me. I can't place it really... I'm not quite sure where to look (immediately), and just seems a little too 'all round'... Information overload maybe? Not sure.
