There's nothing "Dark" or "Magician" about this; this is literally just some blonde chick. If no one told me it was supposed to be Dark Magician Girl I would have had no idea.

This tends to happen when you change the artstyle, hairstyle and costume all at the same time.
When all the context and every defining trait are missing the character is indeed difficult to identify.

Also, what is DMG's canonical eye color? Because I keep seeing both blue and green in various depictions.
