Meant to post this yesterday, but the TAG deadline came and went and I failed. A few days ago, I dusted off an old project I started back in 2011 where the goal was to build a reasonably-accurate version of the Master Chief character (based on his Halo 3 armor design). Started this almost two years ago and then abandoned it. Now I'm determined to finish it for the portfolio, so here's the result of a few days' work.
There is still a ton of little details I have to add to both the armored shells and the undersuit. Biggest challenge is getting good source shots to work off of. I'm using a ton of reference shots (from the game, from toys and models) off the web, from some books I have, but it isn't always easy to extrapolate what a particular piece looks like or is supposed to do. And there are subtle differences in the design from game to toy, to life-sized statues, etc. And then when Halo 4 came out, the design went through a pretty radical redesign (which I like, but I thought I'd focus on the 'classic' look of the character).
Apparently you never get to see what Master Chief actually looks like under the helmet, so I'm just taking a guess. I think, so far, my take on him looks like a weird cross between Patrick Stewart and Bruce Campbell.
