Well, getting the right exposure and proper focus placement shouldn't be of concern to you any more, as you're past that. Now the challenge is to take images that are interesting to viewers.
In the first image, the use of a slow shutter allowed for the moving train to be blurred. Excellent technique. However, in your framing, we see a bunch of railway ties in the middle foreground, a position where you'd normally place stuff you absolutely want us to see. So, given that juxtaposition of a bunch of ties and a moving train, what narrative do you want us to create? Another method of using motion would have been to pan with the train (minimal blur there) and blurring the foreground, which may have given a feeling of speed in a better way, and reduced the focus on the railway ties.
Unless you have a thing for railway ties. Then the picture is almost perfect.
The second image shows a good use of converging lines, but beyond that, what should we be reading into the image? How does the stack visible past the train contribute to the image? How do the trees on the right contribute to the image? You need to now think about the next step in your image making: What do you want to viewer to see, and how will your arrangement of elements in the frame help with that? If the main subject is the star soloist, then the foreground and background are the backup chorus. Hopefully, they're on the same song...
