You did a super job on your grandmother's portrait. Not too much and not too little. Only hint would be to avoid "crossed lighting" by moving your fill light to the right of the camera or right at the camera position. This would make hard shadows in wrinkles easier to deal with.
I was worried about how it might turn out but it really looks nice. Good job.
