@fansy,
I would keep the original. Now, what you say here, "I look at the starry night" sounds like you are looking at a photograph, and I don't like it. What you actually said originally was "I look
up at the starry night". This is more like star gazing, and less like a mere spectator, if I am making a good distinction.
My comment is neither linguistical nor grammatical. It's just the feel of the poem, and maybe just to me.
