See what I would want is the gradient to stretch all the way over same with the space where the quote button is. That way it is symetrical. Also make the sides thinner so the actual area where you post is larger.
Here is the code for my postbit with the double post for anyone who wants to do a quick try of how it would look on their site..
Code:
<!-- post #$post[postid] -->

$spacer_open
