Pose is weird
Makes one arm look shorter
Her hair is uneven with that bunch over her shoulder
She's leaning oddly for no reason
Her mouth is smiling but her eyes aren't
You're shooting from a higher angle- move the camera lower
Move her further away from the wall if possible
Finger and hand position is awkward . Makes fingers look unnaturally long.
If you want to angle, angle the body towards the light and not towards the camera.
Use a longer lens and shoot from further away
Side note- rolling the shirt up seems weird and bleach jeans are out of fashion.
