Here's a sketch I've done just for fun. I guess I've been inspired lately by all the amazing concept art I've seen for Bioshock 1 and the recent cover art for the sequel. I also just finished the game for my 3rd time on hard. Anyway I've decided to do my own personal variant of a Big Daddy.
I'm planning on bringing this sketch into Flash and then do the rendering, shading and textures in Photoshop. Perhaps I'll find some time to do the line work this week but in the meantime enjoy the sketch!
