Cooler yet it's not only visually, it's also a size difference. Things get larger areas and such which will impact your gameplay in subtle ways.
Curious how these things work for Were-forms and stuff like Hydra. Maybe X amount of skills increases heads?
Speaking of druids, apparently your hair color did do subtle coloring changes to the fur of your were-form even. Not sure many noticed this since I assume most only played one character and didn't bother changing hair a lot. I know I didn't at least.
At this point this game is getting closer and closer to Kojima details. Which I absolutely love.
