Concept idea for opening title sequence 3 feedback

Today, I presented my third opening title sequence idea to my class in order to get feedback as to what aspects of the idea were good and where I could I improve my idea. Overall, the story line for the potential opening sequence was received well. For example, the idea that the character would remain faceless in order to create an air of mystery was a well-liked aspect of the idea. However, there were some questions raised as to how certain elements of the opening title sequence would be executed. 

Firstly, one of my classmates asked where I would film the scene of the man's garden. Additionally, another person raised the fact that tea leaves used to make tea are dried, so it wouldn't make sense for them to be used to make tea directly after being picked from the plant growing in the garden. In order to address both these questions, it was suggested that the opening sequence could begin in the kitchen, which would also avoid the issue of finding a suitable space for the garden.  Below are some images of It was suggested that instead of leaves, the man's kitchen could contain poisonous berries which could be squeezed into hot water in order to create tea with poisonous properties. For example, holly berries are poisonous which could be contained in a plastic bag stored inside the kitchen.

One classmate also raised the question of how it would be possible to cast an elderly man given that there aren't any teachers in the school who are old enough to be cast for this role. Therefore, I decided that instead of an elderly man, the character would be roughly between the ages of thirty five and fifty to make it easier to cast someone for this role. Furthermore, the character would wear gloves which would add to the sense of mystery and hint at the poisonous nature of the berries. It would also mean that the age of the actor cast in the role would be less important.
