There is no way to objectively criticize the intention, passion and beauty of the phrases used in a poem, but if you can have an objective criticism about the technique.

All require technical arts, music and singing without it would be just noise, for example, and in the case of poetry part of the technique is to use correctly basic resources such as meter and rhyme. Both are like time for music.

It is also true that we still have a lot of experience to criticize a poem, but more valid than criticizing a know is having the knowledge to fully enjoy a poem because, as the musicians who enjoy reading a score, there's no better pleasure to savor the complexity comprising means to express feelings when we are subject to rules that, instead of linking creativity, fed to result in something beautiful and aesthetic.

I really liked your poem captures what a (a) submissive must feel and how they must feel to his master.

Freedom makes your heart submit. I identify with this line especially for the more free and safe one feels more submitted to his master this.
