Who's your daddy?

Just finished BioShock yesterday. Great game. I felt like I need to draw something complicated and hard so here is our dear Big Daddy... I love that design. Simplified it a lot but still details was pain in the neck. What's funny, there was also a Little Sister here... but she was even harder, lol.

Sorry I'm so unactive lately, guys. I don't even feel able to comment anything I should.
