EXZONE Character Concept Art 1

This is my personal project called EXZONE.
I want to try a different painting and design style in this project.
It is a mobile casual game with a sci-fi background.
The character design is not just cute, but with a bad-ass attitude.
The costume design is a combination of military and sci-fi.
For the UI design, I want to make it look techy, simple, and edgy.
I try to break the "Grid" of UI design just for an experiment.
