Hello, I am glad you are editing Open Street Map! One thing you should look into is "descriptive names" on the OSM wiki. For example, the underpass you edited should not have "Underpass" in the name section. If it were named something like "Alice's Memorial Underpass" on a sign nearby or something, that would be appropriate for the name= tag, but only if people actually call it something in that way. The tunnel=yes tag is sufficient to show that it is an underpass.
