Harley Quinn and champions collection update

I bought and put Harley together yesterday and she's really fun. Comes with a lot of accessories and she poses well. My only issues are that the face and blue spiked thing in the center of the hammer are difficult to swap out. The arm articulation also feels a little limited because of the silver thing around her elbow.

If you want to know where I got them, I picked up Harley at Gamestop, Spiderman at a hobby shop in Memphis, Bumblebee at Books-a-Million, and I ordered Minato on Amazon.
