Sunsets

So I went through some pictures for sunset ones to see what makes a sunset picture good. What is the best lighting and colors. I noticed that a lot of my better ones had a foreground but it worked into the picture and complimented the sunset. For example the pictures of the barn and the sunset with one gold streak. The top of the barn compliments it and works itself into the sunset so that there isn't just an awkward beam of light going up into the sky. I also did an example of too much foreground like in the second picture. The tree and logs don't contribute to the picture but are more of a distraction away from the sunset.
