I liked Bioshock so I found a big daddy stock and here I am... CnC If you look at it please don't be an asshole... Comment and leave something constructive.
IT looks a little oversharpened, when some depth needs to be put into it I do like the flow and colors chosen, seems old timey which is the feel in bioshock
The colours and contrast are nice, but its too small and hard to see. It should be about as big as your current sig I think.
The style you're going for seems a little boring for Big Daddies. Since you like Bioshock I'm assuming you wanted to bring out what Big Daddies are and if you were, you failed miserably. I see no little girl... If you weren't... Ignore the part about Little Sisters. And really, it seems too small for a Big Daddy. The line is a little out of place with a Big Daddy. Maybe a Little Sister line would be more fitting? Mr. Bubbles and all that. However, that might include making your canvas a bit bigger which I think you said you didn't like, so...
