Is this Ardam?

Nah, I doubt it's Ardam. For one, no robes, for two, Ardam doesn't wear glasses, for three (and most importantly), we can see both eyes. I don't recall ever being able to see both of Ardam's eyes at any point in the comic.
I'll allow that, since it's not Webby's style, that it was an attempt at a fan-pic, but I somehow that's not the case.
Good eyes to catch that, and I do see how someone could think it's Ardam at first blush, but I don't see it as being the sexay Mage, myself.
