After a little searching, tumblr told me it's by this artist. This pic in particular isn't up anymore but there's an awesome Cas pic.

As far as I can tell it's by 芥ミチ (at least according to this post, I can't check because of the language barrier/pixiv requires an account).

While you'll likely get an automated copyright claim, you generally won't get a copyright strike which is the main issue you want to avoid with youtube. Pretty much all my amvs on Youtube have copyright claim, but that just means I can't monetize them and in some cases the vid *may* be blocked in certain countries. You can read more about it here:
