I got mine in the mail today, it's neat but I have some reservations.
The figure can stand up straight, but the sculpt makes it look like it's inherently hunched-over. The chest and stomach are sculpted so they look very sunken-in, and it takes a little getting used to. It's a stylistic choice but the ribcage evokes "Holocaust survivor" and I'm not sure how I feel about that yet.
The tail is "poseable" in the sense that it's got 3 segments that can twist, but doing so breaks up the sculpt in a way that a bendy-wire doesn't.
I'm liking the figure more as I mess with it, but it's definitely not my favorite Alien figure in my collection.
