Thinking about it, sunsets can be broken down into categories [of a sort]. One group is the 'Gee Whiz' riot-of-color extravaganzas. They can be mind-boggling.
Then there are the subtle, almost monochromatic ones which depend on the interplay of cloud forms and foreground. #1 falls into this group and is, to my 'eye', a pleasing example. [There are other groups, of course.]
Please do continue to explore sunsets.
