Whoa, I'm "raven-haired" and "dark-eyed", how did you guess. I related this poem to me before I even started reading it.. And I like the sense of feelings and "secrets" being locked in and being one's own.

By the way, the colours (raven, dark and olive) seem rather Gothic as well, which adds to the dim atmosphere.

'That private moment, I regret
My resspass, witness to your secret'-- Very smooth way to put the emotions felt in a moment such as this.
'Glimpse, invade and burn'-- I'm not sure 'burn' is the word yuou were hoping to put in here, maybe 'turn'? If not, then sorry I missed the beauty of the line.

The repetitions work wonderfully here. I can almost see the person before my eyes, so vivid is your description. Touching portrait, skilfully done, a painting made with words.

I like the repetition in this poem, and how you alternate the first line with another physical description. The format is great. :)
