The second shot is not fully realized, imo.
The colors are rather weak from the overhead sun yet seem much more impressive than the curve of the bridge which was almost certainly what you were looking at.
Converting this to B&W and lowering the luminance on the blue and the green/yellow makes for a much more dramatic look. I think.
