* A different artist: Double check the name, perhaps there's a spelling error.
* A specific painting: If you remember any details about the painting, like its title, the subject matter, or where you saw it, it might help narrow down the search.
* A different type of art: The "guardian angel picture" might not be a traditional painting but rather a sculpture, print, or even digital artwork.
To help me find the original painting, please provide more details about what you're looking for.
