You did great writing this poem, some might say that you tried too hard to rhyme though- not that it matters, you got the feeling across and nailed how it feels when you're with that someone

At the center of my world
There's a photo of a girl
With such a tattered, dirty frame
But a beauty of none the same
^^nothing seemed forced here and that is what makes it amazing it was genuine and that makes the reader just go "aww..." i think a lot of people will be able to relate to this to

At the center of my mind
There is no shackle of time
No lonely sides of the bed
Nor flooding clouds over head
^^that is a good thing!!! you do a great job of expressing your emotions here and putting the reader in the state of mind you just described

At the center of my eyes
She's my instant sense of right
Perfect even in her flaws
Without a single scrap of wrong
^^aww i can't wait to find a guy that views me like that! it is rare and unique you know he cares for you than when you can look past the imperfections and still love the person unconditionally

At the center of my soul
There is an ever-burning coal
A fire lit by absent spark
To warm and light my frigid heart
^^:) that is all i can say here

Cause at the center of my heart
There's a perfect piece of art
With such a tattered, dirty frame
But a beauty of none the same
^^ great way to wrap it up! going back to the beginning is smart is makes the poem seem complete and done!

I liked the repetition you used "at the center of" it made this poem stand out i think you did a beautiful job! 5/5
