To put it one way, I still haven't mastered the finer points of texturing. For me, animation was quite a bit easier to learn. I mean, I look at most two-dimensional art and think to myself "gotta be witchcraft", so maybe that's just me. You can learn the basics in mere minutes (grab bone, move it where you want it... easy, right?), but what takes a lot of time is getting better at making more realistic poses and animations, and doing more complicated rigs. My advice is to get a good reference of whatever action you're doing, and really study how the different parts of the body move when doing it. When walking, the arms and legs are the obvious movers, but the spine twists, the head bobs a little, the shoulders move, etc., and all those are things that would be easy to miss, but make a walking animation look very bad if absent. Sometimes you can find a good video online, or even record yourself doing the action, and use that as a reference. There are probably a ton of methods, so feel free to experiment and find what works for you.
