Well as long as you have your own style then you will do just fine!
It's a good piece to start from. Now that you've got the atmosphere and the emotion down in writing, maybe you could start to play with some of the wording to see if you come up with something that sounds better but gives the same feeling.
Take the first stanza for example:
Might rewrite to something like this:Sitting on the cold floor of my prison
Stairing out the barred window
Wondering what life is like
What is in the outside world
Sitting on the floor of my cold prison,
Staring out the window barred.
'What is it like to live?' I wonder.
What is in the world outside?
The punctuation is the third line is wrong, but I hope you see my point. A simple inversion of word order or the use of a different synonym, stuff like that can transform a poem.
You know what you want to convey, now you need to explore how to make the words work for you.
Clan? What Clan?
I'm the Master. I need no Clan.
