Very odd that you would use terza rima in a 11 syllable poem, since terza rima is written in iambic pentameter, or at the very least, tetrameter, not a non-meter.

Nonetheless it is very nice to see someone who holds a poem's structure in high esteem...I think it's wonderful that you strive to make a solid uniformity in your pieces. However, the rhyme scheme kind of breaks at the end...eep. Yes, it does give a concluding 'oomph' but if you are going to advertise your poem as 'in terza rima!' then, well, stick with it.
