Replacing NPC portraits: Do you do it?

Lately I've been ranting about the BG2 portraits a lot because frankly every time I see them I sort of want to gouge out my eyes. I've overridden every single one of mine and am very pleased with my party's appearance now.

Two characters, Nalia and Mazzy, I don't really think even fit their portraits. That's just not how I picture them, and I especially hate the hair. Why is Bioware so obsessed with that same random braided shoulder-length style? I've replaced both ladies with completely different appearances altogether:

This is what I use for Nalia:

When I saw it I immediately thought it was perfect. A young noble girl with a slightly defiant look to her eyes but still overall poised and proper. Her hair is neat and simple but not overly fussed over.

And for Mazzy:

from the original Neverwinter Nights
Just looks far more like a proper knight to me, and I can hear her voice from that image more too. I just ignore the hair color inconsistency.

It's made me curious if others ever do this. Are there any NPCs that you picture differently in your mind? Have you ever seen a picture and thought that it really fits an NPC better than their default one?
