That shot is very impressive, I'd say you have graduated from the course, well done indeed. I like how you've chosen a night time image to make the buttons stand out, and the picture is just stunning, especially with the train approaching.
I'm so sorry to hear of your mother's situation. I lost my mother a year ago, and it's a very painful process. I'm not saying yours won't recover, but the emotions are similar. I'll add her to my prayer list, and you as well.
