Looks good Bjjer!
I know many people have circumvented the smaller stock sculpt on the GA version by simply swapping it out for a strike suit sculpt (as you did), or putting an unmasked, civvy Steve sculpt on it. While it does definitely improve the overall proportions, I've balked at doing either because of the lack of the covered ears on the strike suit sculpt and he didn't have very many unmasked scenes with the GA suit in TWS; only when he made the speech (which they actually made a costume error in this scene by suddenly showing on the GA suit, the same harness with the brown shoulder straps that is on the strike suit and the AoU suit that enabled him to put his shield on his back) and when he allowed himself to be pummeled by Bucky. Plus, I have the propensity to keep my figures stock, anyway.
kds, do you mean you are unsure what sculpt to swap it out with, or you're unsure how to take out the sculpt in general?
