I like this picture with the tree and its bare branches. As I am no expert, this is just an opinion. I think it would have more of a contrast with the colors if your foreground were darker. This could create a type of silhouette. Then the colors in the sunset would be more vivid. Just a thought, Keep in mind it is still a very nice photograph. PS-- Since you like sunsets, you might enjoy some of the pictures I have recently added under my newest work. By the way the sky, sunrises and sunsets are also one of my most favorite things to photograph. Even if it is from the same location day in & day out the SKY will always give you a different scene for your picture. Remember just always have your camera with you. A photo opportunity will appear when you least expect it.
