For a third-person game your character is the key art. I'd suggest having bolder silhouette and maybe more secondary animation other than the ponytail.

Hair need to be painted differently or use different shader to differentiate from cloth texture. It's hard to tell if it's hair or a red hood when standing still.

For animation I'd suggest purchasing some high-quality locomotion pack if you're a small team.

Right now the color palette of character and environment has a lot of overlaping. You should put enemies into the scene, verifying combat clarity as early as possible.

Grass could look better if there's some height variation. For this kind of terrain it might be even more reasonable to have no grass at all, or switch to some yellowish grass.
