I recently tossed Sean Hoade a story I’ve been working on, and he gave me some great pointers to pursue in revision. Among them was strengthening some of the scenes using the below described technique. I found the video very helpful (and am a little sad I wasn’t able to actually BE at the talk, since it was right down the street from me—*deep sigh*), and thought I’d share it in hopes that it might help you too.
Happy writing!
