Don't know if I like the series enough to actually get a tat of it. That Dracula reminds me of the one from that New Grounds skit.
And the second one looks pretty awesome. That's the same insigna I saw in (I think it was) Dawn. I know it was on the wax seal when you got the pre-order bonus with Portrait last year.
If your a fan, you'll be able to know what it is, which makes it even better cause it doesn't have to scream Castlevania and it's almost like a secret membership thing. LMAO
