>>7207326New Widow's tits seem to go out the same distance from her back and are higher, but her torso in general is slimmer. On the upside, she has a nicer ass than the old Widow, as a result of her thinner waist, and better torso articulation overall.
On the other hand, old Widow's wider chest meant her arms had more room to go down, so she could pull her arms in tighter than new Widow can. In posing, this means old Widow has more options for things like holding something in front of her with both hands (pistols, even). New Widow can do this too, but Old Widow's arms when either above or below the swell of her breasts can get all the way forward and even in a little bit, giving her superb forward movement beyond what most Marvel Legends even come close to.
On the other other hand, new Widow has sculpted indents in her elbows so that even though they're single jointed, they have double jointed range. Old Widow has single jointed elbows and can barely get 90 degrees out of them.
And the biggest improvement new Widow has is the weird holster things at her thighs. I have absolute no memory of what the fuck they are or what she does with them, so I'm probably gonna drill through them and turn them into holsters for pistols from old Widow. Then, I'll probably find a suitable head and make Old Widow into Agent May or Quake.
