The coin never looked correct without some detail however, and this led to many changes.

Here are two of the aforementioned initial quick sketches, just for the sake of showing where the original idea for the image started. I hadn't even seen a picture of Jaqen's hair yet, but it was pretty obvious from the books that it needed to be long; the shock white on his left side was a simple redo after viewing.
See, and I made it through this post without spoiling a single thing from the book! Someone call the Citadel in Oldtown and have them send Pate to deliver my prize!
