This piece is all about the depths hidden within someone's eyes, which is pretty common in books, especially romance novels. But this poem focuses on the beauty of brown eyes, which isn't something you see as often. I really love that you chose to focus on brown eyes, and I also adore the wonderful imagery you've added.
Is the rhyming intentional? Reading through this, I'm seeing some gentle rhyming, but it's not super clear if that was purposeful. I think if it is, you should try to make that rhyming a little stronger, and really highlight it, because I think it does add to the poem. Right now, it's sort of hanging in this middle ground, so I think if you pick one side and really emphasize it, the poem will sound so beautiful.
I hope this review helped, and I hope it didn't seem too harsh. You've really written a beautiful poem, and I don't want to seem like I don't love it, because I do. Feel free to take or leave the suggestions; it's your poem, you're the writer, so you know what's best.
I was itching to review something, and this felt like the perfect piece, so that's why this review is a little random, but I hope it helps.
Amazing job, and have a wonderful day/night!
