Aw, Gandalf, such an epic character. I always wondered what would happen if I wore such a hat at school. xD You made him look very old and very tired, as if he's seen too much. I guess that's exactely how I always pictured Gandalf: very calm and wise but also a bit tired of all the sorrow he has seen.
His hand looks so amazing, did you use reference or are you just that epic? I always find it very hard to draw a hand wrapped around something without making it look like the person is not really holding it (if that makes sense).
