First off let me say this is look pretty cool so far. Really love her face and the lighting you have going on. With the stun gun so close, There will be more light on her face.
Guessing she's wearing a leather jacket?
If I could recommend something, it would be to give the piece a bit of a blur while having a more defined face that isn't blurred. Try to give it more of that cinematic look/appeal. Add more of the stun gun blue light to her face. Out side of cleaning up the jacket, I believe you can also add more of the blue light going directly on the jacket with a nice contrast to the black you have.
Did a quick PO to show what I mean. I believe your already going in the right direction.
Maybe my blue is a bit overkill but you can adjust it to your liking if you choose to add a blur. Lastly it would be to find a texture for the planet in the back. Other than that solid stuff. Keep up the good work.
