The closing for me stood out the most because it's not very common, but it fits the story. Like, perfectly fits the story.
I'm left with the feeling that you are really looking forward to what the future has in store for you. I mean, you wrote a letter to it, didn't you?
I would ask the author if these were all things they wanted to do in their future, or if they had just made them up. If they all were true, they could elaborate on each topic more and more and maybe this could even reach a short story-novella-ish length. Why do you want blue and silver at your wedding? Maybe write a response back where your future tells your past what happens.
I really think you could take this piece to a whole new level of you expanded it, elaborated, and maybe even wrote a response. But hey, this is your story, do whatever you want with it!
