After a week and a half of amazing art, it's finally the 12th day of Christmas at ComicsAlliance in our 12 Days of Christmas original art series by the creators of Periscope Studio. We close today with 12 Drummers Drumming, an aquatic hellscape by artist Jonathan Case where a rampaging sea monster celebrates his victory over a massive seacraft through rhythmic percussion.

For more fun with sea creatures, check out the first chapter of Jonathan's recently completed graphic novel, "Sea Freak." And there's plenty of other stuff to see at his website, like his painting of of The White Stripes driving llamas and a new series of videos starring Jonathan's diminutive acorn-headed friend, Hotlanta!
