I see what folks are saying since staring at pics for a while and playing around w. an image program. The original WS maybe captures some of Seb's features better
, tho IMO it's tough because the way any facial feature changes, second to second. And Sebastian Stan I think is difficult e.g. like the directors more or less say, he's capable of a lot of subtle stuff just using his face. So it's hard "freezing" a single expression for a 3-D portrait - sometimes I think Seb's almost able to look like two different people (hope that makes sense) but is still "Bucky". Then there's scaling a human face to 1/6.
But IMO the latest WS - re the latest pics, looks like there are differences in the paint job too

- maybe not unexpected - haven't been collecting long enough to know - but I thought HT was very picky about consistency. And besides, w. the wait on CW Bucky, what was HT doing all this time???
