Please check my Japanese poem?

Hello! I'm writing a poem, and I decided to include a Japanese part to it. I'm a half-Japanese who was born and raised in the United States, so obviously my Japanese is not completely on par with that of a native born Japanese. I'm fairly confident that my writing, romaji and translations are good, but there's always the possibility that I've made a mistake. Naturally, in the event that I have, I'd like to correct it.

(Sorry if this is the wrong category to put this in, by the way. I just figured my question fit best here.)

Some other things I'd like to ask if anyone is willing to answer are:

- Are my brackets good? I mean, are they the correct ones to use for the situation?

- Were any commas I used used correctly?

- Did I use my macrons (¯) right? Are there any other letters that require macrons over them?

- Are there any words or phrases which possess more eloquence that would be appropriate to replace the existing ones?

- Could my translations be altered to convey the meanings of the phrases or words better?

A lot of questions, I know. But I want to get this part right. Anyway, thanks to anyone who'll take the time to answer me. Without further ado, here's the Japanese part of my poem:

「赤い糸、赤い糸」
Akai itō, akai itō
