Congratulations on William, he is very handsome and I'm glad you finally got him! :3
FYI, I had the same arm problem with Arion! D: It popped off and has two tiny splits at the shoulder (and it's his tattoo arm as well which makes it even more annoying!) and it's very stiff to pose, but...it does the job as long as you're gentle with it. I have to agree on the hands though, they do seem very huge. XD Especially when you look at them next to a Pullip!
