The plot seems pretty good so far, but you could maybe add some more description to make it more emotive. For example, in the funeral scene, you could describe tear paths staining someone’s cheeks, or notice how quiet and solemn people look. I like the fact that John gives a speech, but it seems a little odd to me that he finds it so easy to get his words out (I’d imagine him pausing a lot more, trying to form his words properly or stop tears from falling).
I’m liking it so far, and the most important thing is that you enjoy writing it. ☺️
