It's amazing how much detail you can find if you just scroll down. It helps that this is a long picture. I'm not familiar with this comic. That guy certainly looks like a vampire. So...he's just drinking blood for the fun of it? I like how cheerful it is.
Even the Goth looking girl seems pretty happy. I guess it's much too late to wish you a Merry Christmas. The snowflake eyepatch is cute too. I like how it's happy, but with a dark style. The guy with the mask is the best.
