Ahro was taking bust commissions over the weekend, so I figured I'd grab one. This is a lovely rendition of Jakob with long blue hair, a lot closer to his current appearance. Given that most of his life he's been drawn with short hair it's very, very difficult to get people to draw him with the shoulder-length hair he was always supposed to have. This will help things a lot in future.
One of the other alterations is that when Merlin draws him the inside of his ear mostly shows skin, whereas wolves in reality tend to be in colder climes so their ears have a lot more fluff inside before you get to the skin. I don't think I can easily go back and change maybe 1000 or so comic pages where he's appeared, but this is how he'll likely look in other artwork going forward.
