A nice piece of poetry. I'd work on the iambic pentameter, if I were you---it seems like you're one of those who was misinformed about the guidelines of writing a sonnet.
Although the arrangement of rhyme isn't such a bad thing. It might be useful to mix it up somewhat, so that the lines seem a little more co-operative and the themes a bit more rhythmic, instead of a simple aa-bb-cc-dd. Try Shakespeare's or Petrarch's sonnet format, or Spenser's if you're confident with your rhyming ability.
All in all a rather enjoyable read... it's nice to see people bringing back older forms in newer contexts. Kudos.
