I don't very much care for this poem, pardon me. But the kite is not free, the string is in someone's hand. It can fly only as far as it is let to go. A kite needs wind, string and someone to fly. The poem is kind of childish. It has no substance.
Samra, your strict rhyming scheme contrasts very nicely with the image of the kite as it flows freely through the air, I liked this very much. I feel there is still a little work to be done on some of the lines as they are a little clumsy in construction but it would be worth doing this.
