1.) i think the leaves are too defined, maybe you shouldn't outline every single leaf as it could make the pixeling process a tad longer
2.) there are too many light sources on the trees it should come from one direction instead of multiple directions
e.g: if the sun is at the top it should be on the top of the trees, if it's at the right the light should hit the trees on the right side while the other side is in the shade , like when the earth is not facing the sun it's covered by complete darkness
3.) maybe the bark could be changed a little bit it sort of looks pillowed.

theres a part in the animation where her hip disappears wasn't sure if that was your intention or not looks pretty good so far.
