Yes, at least someone who noticed it! There are only a few people who knows the storys! Terry Brooks books are so epic, but here in Germany he is not so popular! It's a pitty! I have read all parts from Shannara and I love them very much! And Allanon was always my favourite character! He has a dark, mystic part on him and he do what is necessary, although he knew the consequnces, even as it means his dead. I was very imressed by him, so I choose his name for my profile in many videogames as character-name.
Well, I for one think making yellow wolf eyes for them would have looked really nice. Not glowing eyes, but normal eyes. I don't know about the "too obvious". They don't need to glow, just have the coulour so you see they're yellow. I'm sure an artist of your caliber could figure out a good way for that, after a moment of thought.
