+1 on signing me up for practice
I love the ghost flame look, I want to do that to my Meanie (looks awesome on the Candy Spark Gold).
Resale.....beauty is in the eye of the beholder. If you do some very tasteful and subtle ghosting my opinion is you may get a bit more for the paint if you were to sell. I personally would never buy a bike that had a bunch of skulls or bright paint work on it unless I could get it cheap enough to repaint it, but that might be someone else's cup of tea. If you don't plan on selling the bike, paint it the way you want it.
