Dean drew Lori traditional style(Although I think he digitally coloured her), without a colour palette and at a fairly large size. So, when scaled down and altered to fit Jazz 2's colour palette, she looks a little strange.
Here's some(Maybe all) of Lori's sprites at the original(Larger) size. Keep in mind that there's no antialiasing because Dean knew she'd be downscaled, which would make doing AA before that unnecessary. You can see a lot of detail in these that was lost ingame.
