@JoePublic and Zev0: thank you very much! They look very good! And now that I see your work, it comes to my mind maybe one of the reasons why my arms-crossed M4 always looks to horrible might be I'm doing something wrong with the arms, so it could be my own stupidity rather than the shortcomings of the figure itself. I'll have to look at it again. But your versions both look excellent. The slow-thing: I don't have bought any clothes for M4 and don't plan on using anything for the upcoming figure, whatever I might be buying, so this is not really an issue for me, though total 60 min for conforming an entire clothing set is ... slow, yeah slow :(
