I'll leave it to native English-speakers to write a detailed criticism, but here is what I spotted:

"As far as he new life, it could hardly be a blacksmith"

knew (a mere typo, I know )

"Nevertheless now and there"

Don't you need a comma after nevertheless? And I suspect you wanted to say "now and then", didn't you?

"This was the sound that none of the animals could produce."

I think that "a" would work better here.

You poem is great, and rhymes are good, but the meter in the first line is broken. Don't forget that "mere" is a one-syllable word.

Also, "a thing with what" - sounds wrong to me.

My error-bell rang in some other places too, but I think Pravit and others will make a better job of correcting you than I possibly can.

But a great job nonetheless
