The right hand is mainly done for Season 1 of Dexter because of the happy face blood slide that Rudy Cooper/Ice Truck Killer/Brian Moser left for Dexter. I did the logo for the show on my thumb nail and blood splatter on all of the fingers except the middle. That one is for my second favorite season, Season 4, where the Trinity Killer had his day job at Four Walls, One Heart; that's the logo.
The left hand in Fuchsia Fling, Greenwich Village, Funky Dunky, In My Back Pocket, and Ogre the Top Blue is done for Season 1 of Dexter with the Ice Truck Killer. Hard to explain if you don't watch the show.. I did this again because that prosthetic hand always seems to come up somewhere and it turns out it's back for Season 7!
