Retro Sci-fi Big Daddy Sketch

This is a piece of fan-art based off of Bioshock. The concept involves the combination of the Big Daddy and certain Retro Sci-fi elements. This is the first of four sketches, and by far the largest. This particular character isn't strongly based on either of the Big Daddy types yet shown. He carries a Geiger counter, long since broken, which he would gladly use as a handy blunt object in the process of hunting and destroying whatever or whoever he pleases. Nicknamed "Geiger" or Watcher" types, these Big Daddies are outfitted for activity in radioactive areas, and have very powerful senses for tracking, following, or observing opponents or intruders. Despite their appearance, featuring sturdy metal armor and a large lead apron, they are able to keep rather quiet if they need to.

As I mentioned before, this is one of a few sketches. I may combine all the rest from the same page for another submission.
