Sixinchplus has made some beautiful Coipel Thor heads too. I’m gonna be happy enough with the Max as-is to not want to spend the extra money, but I’d definitely bite on a flying/hair-back 3rd-party head.
I think the ugly hair and oversized hammer are what's gonna keep me from buying this at full price. Everything else looks nice and I do like the outfit. But I'm not sure I wanna buy a figure at that price I have to try and find replacement parts for out of box.
Sculpting (and drawing) hair is very difficult (especially the "wispy" hair look ), and it is also underrated as to how much it impacts recognizing a likeness. Definitely the un-helmeted hair on Thor doesn't come across great from some angles.
