Alucard from Castlevania

This is a special request from my friend who wished me to draw for him Alucard from Castlevania
I've never played it before, but Alucard is the son of Dracula (a vampire) and a human woman named Lisa. He was raised by his dad and taught to fight for his dad, but he rebelled and sided with humans. He changed his name to be the opposite of his dad's name and fights against his dad's evil armies as Alucard. His original name is Adrian Farenheits Tepes
