You developers did a great job spriting everything, but in my opinion, I believe that the guide's hairstyle as the NPPlayer, should be Hair 14. Why? I personally think it looks better than Hair 2 and a little more fitting for the guide.
And I have realized several references to the terraria webcomic "The Legend of Maxx" and those are some good little references. Like how the guide is mentioned as a "Book Worm" by the arms dealer. And the NPP of him is a mage with several magic skills. Or it was the developer's idea to have him a mage, either way, nice idea.
