It's really inspiring how much work you've put into this. The final is looking great!
I don't know if it's too late now, but I think the composition might have looked better being portrait instead of landscape. I say this because it would give your character a stronger focus. At the moment I see your character first (which is good) but then my eye gets confused and is led outside the painting. As for the storytelling, it's hard to tell what's going on. Is she being ambushed? Why is she posing like that?
I really like the the mood and atmosphere you've created with the colours for the forest. Love how you painted the rocks. Really awesome. I think your character could stand out a little more though, at the moment there are some areas such as the waist and feet that blend into the background. Other parts of her look kind of flat and could use more defining of the forms. The lighting seems a bit confusing too. I think the light is coming from the front, yet it feels like it is coming from behind. Her legs don't look like they're in the shadow.
The character design is great, and the amount of effort you've put into it is really motivating for me. Great simple colour palette and nice use of shapes.
I'm sorry if this sounds nit picky or discouraging. Especially after all the hard work and hours you've spent on it. I hope this will help you for your future pieces and I wish you the best of luck on the competition!
