1. Due to too much blood and such, the small versions of the portraits are (almost) unrecognizable when at less than 25% health, with the red tint on them and all.
You thought so? I thought they looked alright, but hey.
2. I didn`t want to go overboard with the mutilations. 
I always kind of thought the overboardness was part of the charm. It's fun in the same way as watching the 300 is fun. I'm not sure anybody's going to take this mod that seriously.

3. I know Ana`s busy with plenty of other things, including RL, so I didn`t want to bother her with these - she was very nice about it when we asked permission though and she did offer to help, but I thought I shouldn`t push her with this.
Well, Ana, if you ever feel the urge to bloody up some more NPCs...!
4. I wanted to make a mod already!
Heh, yes, I definitely hear you here, and I'll say "good work!" again.
NPC Damage was very much my Duke Nukem Forever.
5. As you mentioned, consistency issues. The ones I made are quite different and that fact would have been glaringly obvious in-game as well.
I think both sets are excellent edits. If Ana ever finishes hers I'd be very interested to see them as alternatives.
