It really looks incredible. I am very excited about this pack, I'll play it as soon as it is released.
As for some feedback, everything in those last pics looks amazing, especially the masks, except for the dark mask between the mailman's mask and the bomb mask, which looks kind of flat in comparison to the rest, and also the great fairy mask does not look as "bright" and clear as the rest, which make those two masks stand out in a strange way. All the other masks look great.
