Taking pictures of sunsets is one of my favorite things to do. You're just there at the right place at the right time and hopefully have something to capture the moment with. My biggest frustration with it all, it's so hard to capture the beauty of nature without the clutter of man-made crap getting in the way. powerlines, Cell towers, lightpoles, etc.
My favorites are #2 from @strawhat, and #3 from yours @acidyo.
A good way to boost the colors in a phone camera, I have Samsung S5, is to put the white balance on "cloudy" for sunsets. It will let the camera capture the colors richer, closer to what you see in real life, and still no post photo filtering.
Glad you took the time to stop, enjoy, and capture the moment.
