I like this poem, and the wording of it, but it has not followed the rules of a rondeau, as far as I know them. They are much more complicated than your statement reads.

They should first have 8 syllables in each line, except for the two refrains which should have only 4 syllables.

I do not see the refrains in here, which should be the last ( 4th ) line in the second stanza, and the last line of the poem. ( these should be your rhyme C's ) These refrains should also be the same words as the first half of your first line, although sometimes poets use the second half of the first line.

a rondeau should only have 3 different rhymes ( a, b, and c ) which you have 3 of here using "ight" "ow" and "ie/y" but your 3rd line in 2nd stanza has a 4th rhyme which doesnt match any of the others " saw " Following the correct patter this word should be "ow" ryhme.

This definition might give you a better understanding of what I mean...

The rondeau consists of thirteen lines of eight syllables, plus two refrains (which are half lines, each of four syllables), employing, altogether, only three rhymes. It has three stanzas and its rhyme scheme is as follows: (1) A A B B A (2) A A B with refrain: C (3) A A B B A with concluding refrain C. The refrain must be identical with the beginning of the first line.

Like I said, your poem is actually good, it just doesn't follow the rules so my advice would be to keep it as a free style poem, or to challange yourself to turn this into the a rondeau by changing some things in it.

Hope this helps.
