Walking, running, and sprinting with magic equipped looks like your character had an accident during his/her last fight and still hasn't cleaned up the mess.

It looks ridiculous, yes. Yes, there are mods for the sprint and running animations, but I've yet to see one to fix the walking animations. Unfortunately those who play on consoles will have to stick with the horrendous animations that Bethesda used. I only wish I knew why they though that particular animation would actually look good.
