That is an awesome job! I love paper mache. I don't know a lot about the Day of the Dead and the traditions that go with it but I think it's great that you are honoring your grandfather's life.
It looks like you had a lovely garden! It's great that you take the time to save the seeds, a lot of people don't anymore. My apartment is under pine trees that seem to shed year round and I have a trouble growing anything Maybe next year...
The sweater is lovely, the ribbon is a nice touch! I especially like the ear warmers, did you use a pattern? I am a self taught knitter and haven't advanced my skills to sweater level yet!
