Well, you are totally on the right track for sunsets: something INTERESTING as a foreground silhouette is a big,big,big help to elevate a sunset and give it some sense of place, of location; although the tree is not ugly or anything, it is a bit distracting, but the Ferris wheel is a great object for the foreground silhouette subject, and the "Magic" sign is good too...That Magic sign on the pagoda-like structure would have made a good foreground silhouette object. I give you props for putting something in front of the sky in both of these shots. A sunset of just clouds is pretty boring most of the time, especially to viewers who have no connection with the scene or the photo.
The floodlights are actually well-handled! Great exposure on them! That's actually an interesting man-made/natural juxtaposition!
