Well since it has been a year I'll do some good ol' fashioned nit-picking.
1) Angel/Snow-Angel - In the second frame he just looks out of place hanging in the air, but aren't they in a house/office at this point? It’s just out of place the fact he's either flapping in the face of his teammates or he is just hovering. I think standing in an action position would have looked less out of place.
2) Professor's X-mas' beard- It looks like Cole's collar has a cousin and it’s the Professor's beard. I looked at the other drawings of his beard and there was no line to indicate and bend or fold yet in panel 2 his beard makes a 90 degree turn. I know there are some looping lines in the head-on shot but nothing to indicate his beard has that type of turn.
Otherwise the story remains in medias res and I am hoping that there is a punch line as a cliffhanger for the weekend instead of a dramatic pause. Also, hearing Santa having balls to do something is strangely disconcerting.
Well i hope you guys (and gals) enjoyed these nit-picks and happy anniversary PVPMMS!
