I like these shots travis and they do clearly show the dramatic change within minutes as the sun sets.

But these shots are taken at the end of that 'golden hour' where it is way to dark to see details. 45 minutes before this is AMAZING light for many more subjects including portraits.

Just as an FYI - The golden hour refers to the first hour of light and the last hour of light. The light is softer at these times due to the sun's lower angle.
