I just started writing a poem, and i wanted somebody's advice to improve my poems. But this is what ive gotten so far.

"Although i just met you, I felt as if i knew you.
As if you were my very own, I look at your picture every day and night; Night and day. Not a second goes by that i ont miss you.
The angels in the sky above took you to a whole new world. I believe that one day, one day in the future ill see you again"

I feel as if it is more of a letter type deal, instead of a poem. What are your opinions?
