Oh! I like how you have interpreted Wiz so far! :P
Or in other words: Interesting... hand.
Concerning the old form, I wouldn't want you to change your mind for me, but it is the truth that Wiz has been drawn much more in his old form and there's yet to come a good drawing of his young form (well at least one that's more detailed and focuses more on him, if we account the Wiz by James that we can see on the background, which is quite good).
Seriously, do not let this affect you, it's just a comment. I wanted to make a drawing of his young form, but I've been facing some difficulties, but maybe I should try more, so that it actually happens.
On second thoughts, that drawing by Dagget included a version of Wiz that does not have a beard or long hair, but his face looks a bit old, so I'm not sure what to make of it.
Here it is:
I always liked this one.
