I made a little edit (not happy with the clothes but I spent way too much time on it haha
), not sure if this helps.
The edit looks cool. I like the texture you gave the hair.
I tried to improve the texture on the hair using your edit as a reference.

I not sure directional shadows would work in this game. The shadows would look fine when you are outside but stop lining up with the light sources when you go indoors.
Its hard to tell what exactly this scene is about.
Perhaps if u explain what we're looking at here we can help make it look better.
For example:
Is that a crystal at the top or some water?
What is the ground supposed to be made of?
What are those 2 big grey lines on the right?
Is that some natural rock formation in the background?
The idea behind the scene was the player standing on one rock bridge looking further into a canyon with several floating islands and a bridge in the background. With a setup like this:

The two lines to the right were meant to be the cliff meeting up with the rock formation the player was on but it didn't turn out very well and didn't make a lot of sense.
I tried reworking some of the image but I don't know a very good way to give detail to the rocks at a distance.
