We stick with official art/screenshots, even if the images aren’t the best.

Accoring to Scrooge McDuck wiki, this is a real picture.

@Paperinick one: we are not the Scrooge McDuck Wiki. Maybe you would be happier editing over there, since their style seems to line up with yours. Two: that picture looks to have been made using the old DuckTales 2027 character maker game or something like it. It looks pretty spot on, I’ll grant you, but it’s still not an official depiction of Quackmore.
