Hey, great work so far! Let me share some ideas with you, you are free to ignore them, but i think there is a room for improvement.
- I think the ambient, front light is too bright, the character would look better if illuminated only or mostly by the thunders from the sides.
- The background spike-like element is distracting a bit, I believe the simple starry night background would be enough.
- As an air hero, she should be flying in the ari, not walking on the ground
