Align usernames & comments around avatars

I’m using the options theme and the shadow subtheme or template or whatever they are referred to lol. I believe the official site requires paid support which I cannot afford.

I’d like to figure out how to make picture #1 look like picture #2, any help would be greatly appreciated, as it looks quite silly the way it is now.
