A dove and a man

[Brownlie]

He watched the earth -He can often be improved upon by replacing it with the name of a specific person
and His eyes were filled with fear
How can love and joy that easily dissapear - You have an unfinished question or your syntax is messed up maybe get rid of the word "that" and adding a question mark
They dream of wings; they dream of skies
Why would a man want that disguise?
They always desired to follow Daedalus's steps -- Are you referring to the flight of Icarus here? If so, you kind of bring in the mythic figure but don't really say much about him.

Why are people so shallow? -This question is very general and doesn't add much to the poem.
After so many years you still are so callow! - Remember to consider meter when using rhymes.
Can't you see?
You are bound to earth, you can't break free!

And, near the man who desired a disguise
Strolls a beautiful dove
Who, with her glorious wings, was meant to rise
Though She never could have
All her life she wept for this moment
A walk on the earth;
A dream of her own

And he still looks for them
His eyes still have not forgotten the fear
But he knows why aren't they satisfied -There is something wrong with your grammar in this line maybe your missing punctuation.
They are not themselves and they search for truth - Who is they referring to?
For something they hold dear
Which will forever be
their eternal youth

This poem is very messy and confusing but with some work you might be able to improve. I suggest looking into using meter. To write good respectable free verse means that you are being innovative and that would imply that you still know the existing poetic tools. Good Luck.
