While I appreciate the 'about to do something interesting' this is hard to capture and if all models are doing it not as noticeable plus I feel very few of the old sculpts did this. Much like if all models are doing action poses, currently in the plastic range this is not the case, some minis are still very static.
For me a mini is not about 'what a normal person might be doing most of the time' but what is a 'caught in the moment' pose. Mini games for me are about action, and those moments of action, that should be the normal for when they are actually in the middle of a skirmish. The characters in Malifaux are certainly not normal people to me and probably aren't doing normal things most of the time (well maybe minions and peons). I like the pulp action feel of the new minis.
I will agree the old Perdita is a good 'tension pose' piece. Models with tension are good. I would like to see an updated to finer sculpt plastic of the same pose. Same with snapping on a rubber glove. I think the pose should reflect the character of the model. Lady J's fiction is rare that she is standing around, she is 'on the hunt' at least that is the way she feels for me which is why I like her new plastic. Hair might be a little much but its part of the current 'pulp action' style Malifaux art is and I can appreciate that as a choice. For me Lady J's normal is on the hunt, particularly 'in game.'
I think overall the new line of mini's is a lot more interesting. There are exceptions of course but most seem to be in the middle of something interesting or are telling an interesting story about a moment or scene. I don't feel a lot of the older metals did that as well with some exceptions.
