i prefer #2 over #1 myself, as i like the way the trees on the shore guide you into the mountains in the background with the reflection of it on the pond. the long exposures add a subtle bit of of smoothness in the water. #1 just isn't as interesting for me. the reflections are nice, but it lacks the impact of the sweeping pano of #2.
i think i would keep the blue cast. its a little flat and boring without it. i think it gives it the context of being in the evening.
