It's not bad for your age. I think I like the lines "I felt as if I were an eagle, Flying without fear; As other birds looked on in awe" the best. That is probably because I like writing poetry about birds. I started thinking about a flock of pigeons who stopped strutting and pestering someone with a bag of stale bread crusts, to look up and coo at an eagle passing overhead. Then I thought about a flock of nervous, shy mourning doves sitting in a row on a telephone line, who saw this eagle in the distance, then when it passed they held their heads up a little higher--one because they were safe, and two because they noticed the eagle's posture and flying technique. So maybe you could write a sequel to this poem and go more into details about how being an eagle influences others.
