At first I didn't notice the changes in Samus body; she got less boobies, more muscle, but after someone pointed it it was pretty easy to see.
I'm neutral with the change... like I said I didn't even notice it at first thou keep in mind I don't play Smash so I have little frame of reference.
Which one "fits" her more is hard to judge. I don't know how much of her physical prowess is helped by her power armor but I don't think it's out of place either.
I think she looked fine with bigger boobies thou, but she doesn't look bad with smaller ones either. She is closer to what I think Angie cup size would be and I think those are a fine place to be.
Still make up for a (very) silly strip I guess.
