Greetings @wilfredocav , excellent photographs captures, I like very much how you define them and explain their basic fundamentals and give your criteria and reason why you took them, I am just starting to take the habit of photography and I like very much how you express yourself to describe them, I still have many concepts to learn, many theories to study, but little by little I will acquire the experience.

The effect that the sunset generates due to the backlight as you mention is something beautiful and I like it when it is noticed in the photographs, the photographs where you see the green area I also liked, nature itself is something very beautiful to capture its essence.
