Sapphire has a nice one in the new bundle. Otherwise, if none of the FCP plugins work, probably bring it into photoshop. There are some great ones. Snap Art is perfect. I’d apply to a 2nd layer and tweak the opacity and or apply on one channel only to be more subtle.
Also, think about background blown up with a gaussian / illustration effect, etc. with a normal foreground picture.
There’s a lot of tutorials around for that too.
