I really like your ideas and I can see what you have been thinking. The composition are great, although there are missing a few things (straight lines, light).

1. one is really great. I like the light and the post processing (It works well to make a dirty and dry environment)
2. one has a good composition but you have to rotate the photo a bit.
3. one is way too messy for me.
4. one is like the 2. one. But in addition I have to say that I do not like the shadow on the left side of the photo.
Have a good day.
