That first animation was pretty good, good camera effect and walk, for the other one, looks like you didn't put much effort in it.

You're problem is smoothing, easing and reactions.
I'm pretty sure you already know the concept or smoothing.

Just go take a look at every tutorial you might find useful, especially at Baha's one.
And practice alot too, I can garantee you that you will improve greatly.
I do not demand for Courtesy, since my thread as died.
