Seeing as the Witcher line is happening, I certainly would love to see a few monsters made, but for now here is what I would love to see, and would be my suggestions on the line.
I'll begin with the one's I'd be most stoked for (Geralt isn't on the list as I have the statue from the Collector's Edition)
My biggest want would be Ciri, and for her as an exclusive, I'd suggest her Zirael/Flash that Cuts Silver sword, or/and a change of head including her winter hood.
My suggestion would be a facial expression like this, possibly even a similar pose.
The winter gear that I mentioned, which wouldn't change the body at all, so a fairly cool change of head.
Next would be Triss Merigold. As for clothing, I'd suggest Witcher III clothing, same for some of the other characters like Geralt or Yen.
An exclusive would certainly have to be a magic powered hand of sort, with either flames like picture 1, or even an orb shaped ball like picture 2.
Still on the note of clothing, I'd prefer her DLC suit over her initial wear, but that would just be a fanboy dream lol.
Now to Yennefer. My suggestion if she was made, would be her in-game face; the rendering and concept seem almost too brutish, even though she is considered to be inhumanly beautiful. Her exclusive could be a crow in hand, or again, some form of magical power. Maybe lightning? And lastly her clothing, I'd recommend the DLC, but unlike Triss either the original or DLC looks good.
The face and dress of this: yes please!
If her necklace also lit up, that'd be cool, but I feel that would be a necessity.
Lastly, her powers as accessories. (Clothing like this is also good, but I'd pass on this sort of face).
Got a few more suggestions, but I feel this is a large post as is lol. Though I'm just excited to get any Witcher at all!
