+1 for everything in this thread.
For those saying they shouldn't look like skinny children: they should look like you took an adult human and scaled it down equally in all directions, not a child. Like what happens with regular everyday humans... a 4'8" gymnast doesn't look you took a 6'8 basketball player and squished them down weirdly in one direction only.

NwN2 did a decent job of it.
