Beyond eye color and a little bulk, is there much other difference between her normal self and her "were" self, bodily speaking?

Her fur is definitely a lot shaggier/thicker when she's a werekoala and she is taller, as mentioned as a werekoala she is muscular, perhaps a bit more than normal and she has much longer claws and her eyebrows are thicker (basically this is a nod to a werecreature lore thing where a sign of one person being a werewolf is having thick slanted eyebrows that meet in the middle) and she definitely tends to be taller and has a much bigger breast size (not cartoonishly large or anything, but specifically big enough to support her muscular chest and body), and also she sports sharpened canine teeth which resemble fangs and has much longer hair...this hair is messier and has what is known as an '80's style teased look to it.

Well that's a very thorough answer!
Color me impressed lol
