Definitely the animation. I can hold my own at geometrical programing, but I just don't have your skills. See here, I managed to make a walk cycle. Unfortunately, that piece of junk came out when I was trying to make it run. Now the animation I have for running looks like crap. There are millions of walk cycle tutorials... and about 0 running ones.

BTW, as I said, I am a bit of an Anglophile, so I like that you noticed it was British! Actually, I think I'll use it more often now!
