awseomeness! Thats such an inspirational poem...

The repetition is very effective. I like this because, even though it's in free verse, it has a certain rhythm that reminds me of the tramp of heavy boots.
There are a few lines I don't like:
"Gliding, diving, rapidly descending"
This kind of parallel construction is really overused and generally hokey-sounding (at least to me), by which I mean rather ugly and uninformative.
Contrast it with these lines:
"He stoops and tries to scoop / the liquid metal into his rough hands"
This is very descriptive and gives a strong image of the hero with very few words.
