Overwatch hero concept

Overwatch is a game I have played a lot and I wanted to create a concept for a character. I settled on the junkers as a basis which in the Overwatch lore is basically all of Australia. I imagine this character would be a support with her gun being able to swap between healing and damage mode. I have also included the original mock-up of the character which admittedly is quite rough but I think it is cool to see how it started.
