I think animation changes are something we're going to have to rely on mod makers for. There are a lot of animations I'm not happy with (the ridiculous jumping sneak attack - both melee and ranged is the biggest offender). I'd love to see a variety of walk/run changes, monk jumps to include a flip, a variety of sneak animations that don't look goofy half of the time and... well, you get the idea. Some races/classes get nicer animations than others, so I'm sure when modding tools are released, we'll slowly start to see swapped animations etc.
