1. Maybe move the logo to the top left on the letterhead because the tail is causing a weird thing with the natural border at the bottom. I'd ditch the lines too. They don't add much and aren't prevalent anywhere else.

2. Can you flip the phone number so it reads upright? I think you can dump the words "Address", "Phone", "website" as well. They're pretty self-explanatory.

3. Take the line "burlesque hall of fame" off of the back of the card at the bottom.

4. I like the open and airy look of the style guide. Just make sure you maintain a rigid grid everywhere and purposefully align things where needed. The colors page feels like they are pushed to the left too much.

5. Remember not to break any rules in all of your branding pieces that are documented in the style guide.
