I think this animation is quite nice. With my only sticking point being I think Beth's face looks a little off.
Comparing it to what's in game currently, her mouth looks off center, and her nose looks too small. I do realize the mouth being where it is could be because of the angle, but I still wanted to mention it.
Also I know she's looking down, but her being cross eyed doesn't help with the goofy face either.
All n' all, I think once you get the hang of the animation program, and if you try and keep the animation art style as close to art style already in game. This will be a good addition.
