I picked mine up from the Post office last night. I think overall she came out really nice. Here head sculpt looks good, while not a dead-ringer for Liv, she is recognizable and certain angles are better than others. I don't love the mixed media hair but it is better than Tauriel's. and the outfit is well done. She literally needs no futzing out of the box to look good.
All that said, I do have some complaints and this is mostly from a value stand point. I feel this is the lightest figure in terms of what was given for the money and it feels rushed. She costs the same amount as Eomer or Thorin who have super detailed, layered outfits, come with lots of gear and accessories and are just really impressive.
With Arwen we get a cool sword, a cheap scabbard with no where to put it (no belt, harness, or rig) and then a bunch of hands, a number of them seem like they are from a knock off Scarlet Witch figure casting spells. I don't recall Arwen ever making these gestures, even when summoning the water spell so it seems like they just threw them in to fill out the package a bit. I also feel that while the outer riding coat is nicely done, it is not the thickness/heaviness of the outer coat and she seems to be missing a layer between the lacey bit and this coat.. they sort of combined her dress and coat into one piece and I wish she had come with a heavier outer coat and this could have been the under dress.
I don't know what else she could come with but this seems the weakest of the offerings from that standpoint so instead, just knock $30-$50 off and it would have been a much more acceptable package. The instructions literally show you can swap the hands and the sword fits in the sheath. The just filled in the instruction booklet with standard AF stuff to make the package seem more than it is.
Still happy I have her but after the wonderment of unpacking Bilbo, Thorin, and Eomer recently, this one just fell short in several ways including the hair methods.
I am curious where they are going in the future and wish we had a better road map as the plans that were laid out in the early days have surely taken some different paths and now it is hard to say what they will come out with. A number of the Fellowship themselves have not sold out so it is hard to hope for second tier characters and the like. We heard about Faramir, Azog, Sauron, and Lurtz having been in some sort of state of development but beyond that, not sure what we can hope for. They really slammed these last four out (they were only previewed in July of last year and here they all are plus Arwen).
