Simile in an unrhymed 7-10 lined poem?

This might now be the best one you have see but hope it helps :)
I am like castles on a hill.
Almost like birds above the sky.
To think I am like bricks hard and fine.
Just Like birds when they sore through the clouds on a stormy night.
The hills are like my guards standing to protect
Similar to birds and the sky is like there knights.
I like the way I stand just like birds upright and having delight.
I just made this right now so I could use tweaking but hope it helps. :)
