Reblogger and author look similar, their roles are unclear
It's not obvious why a reblogged post has two identities at the top, especially if the post is short: the reblogger and author have similar size avatars and the reblog badge on the reblogger's avatar is easy to miss because it's a similar colour to the avatar background.
Maybe it would help to make the author's avatar smaller (perhaps the same size as the commenters' avatars), and/or add a divider between the reblogger and the author?
