This is amazing. I've had a similar experience with my own grandmother. She died right after my parents were married from a brain tumor she kept secret from her family until the end. A couple of years ago, in my HS art class, I drew a portrait of the three of us by combining pictures of us. My mom says I'm a lot like her, as well; my grandmother's sewing skills skipped a generation and now I'm going to school for costume/apparel design.
Again, awesome work.
