I adjusted the levels of the first picture a bit to bring out the water a little and darken the sky a bit. I really like the composition of them though!
Personally I think they are both underexposed. I took the liberty to edit the first one. I bumped the exposure and warmed it just a tad, then went back and burned some of the clouds. To me, golden hour should feel warm, and there is enough light there to not have a dark photo. Just my opinion....
