I like this guy's reinterpretations of Touhou characters in general, but this one bugs me because it doesn't retain the essential color scheme of the character, which is an enormously important aspect of how they're all designed. ZUN isn't a skilled illustrator, but in terms of choosing recognizable design elements, he's the master.
On the flipside, this is still a good illustration, and it's still got Patchy's personality, even if it's off-palette.
