I've seen a few images like this under the toloveru tag. Should we have some kind of tag for images like this where the artist redoes the character from the manga and then overlays it back over the scene?

I'm 99.5% sure these are traces/colorings done by a fan.

vector trace already exists. There is more going on here (something like 'vector overlay'), but let's keep it simple.
