That blue shirt you made looks great! I think it is PERFECT! My only suggestion is that the sleeves might be a bit longer so that his joints don't show.
The vest material seems to "sweater like" to me. Does he wear a sweater, or more of a burlap bag? I'll have to look at those pics IM recently posted. Not sure about that vest just yet...
I could make them longer--I was just trying for screen-accuracy.
