When does manga become manga?

If a westerner draws, say, this:

It counts as a drawing done in a manga-style. Why not manga? When does it become manga? Is it only when a native Japanese artist draws it? If so, if a Japanese person drew a standard smiley face, does that count as manga?

manga = comics. 'manga-style' doesn't exist.

like he said, there's no such thing as manga
Picture this, what if every country on earth made some form of comics?
Manga is called manga because it's unique by default.

Wait, so when people say 'check out my manga' it doesn't technically make any sense?

We call the jap stuff manga because of the "style" its done in with layout. If a westerner draws something it = comics.

and korean?

Manga means comics (or cartoons). People use the word to denote Japanese varieties because it's a Japanese word.
