I modified Justin's shoulder a little, rotated his arms inward, and I think it looks like a better neutral position. For Brad, I made his head bigger, changed his jaw, lengthened his shirt and arms, and I think he's closer to the proportions I'm after. (picture at the end)
I pretty much drew Cody and called it a day. The hair seemed too big, so I modified it a little, but then I messed it up, and now I can't get it to what I want it to be. So, it's good enough. I feel like he's more colourful than the others, but maybe that's crazy-talk.
