Have you sent the application in yet? If not, I'd be happy to take a look at it. Actually, even if you did, I'd still be happy to take a look -- jynx@n2mail.com .If sending in a follow-up letter makes you feel better, go right ahead, it probably won't hurt. I'm not saying that it'll help, but it won't hurt.
As for it not being an active reflection, of course it isn't. It is, however, a gague of how well you can formulate and compose your thoughts, as well as a basic check to make sure you really can read and write. I know it may result in a bruised ego, but the admissions folks will probably look at it and say "Yup, whiskey here can write, he knows where to put his commas and periods, and he can string two sentences together without losing focus of his subject matter. Good enough." I doubt that they will actually sit down and discuss your essay in-depth, and make a decision based on that. More likely, they will look harder at both your grades and your extra-curricular activities than at your essay's subject matter.
Ugh, enough talk. Don't sweat it too much, but if you're worried I'd be happy to take a look.
