GMing assessment

Last weekend I ran my regular Savage Tide game. I noticed that I wanted to do a lot of high-level explaining about the setting to give context to certain events. I also didn't do very much in-character style roleplaying. I said a lot of things like "he says that no one else has been in the room since this morning." Makes me think I need to fill out my Naughty List and do some self-evaluation.
