I much prefer the colour in number #1, however I am a fan of long exposures. What was the exposure time in number#2 ? If you have the time then you should take several shots at different timings and don't be tempted to always use the bulb mode. If you do then you then you will get less images and longer isn't always "best". Experiment and use your judgement afterwards. Sometimes taking two images - one as was for the sky and a long exposure for the water - and combining them works. Don't be put off by some who think they aren't "real" because it is photographic art you are dabbling in.
