I like how you were able to almost deconstruct the ideas in each of your products, and build from there to accentuate in different ideas. I think your process of coming to ideas that were novel/feasible/valuable was good.
I wish that some of your ideas had deviated more from the base product, just to see some more unique and strange ideas. I would have liked to see what you had come up with beyond more grounded modifications to the products, and more loose associations into new ideas.
What if you had taken two of your pre-existing products and combined them, extrapolating from there new product ideas? Either simply adding the features of one to another, or taking features from some and adapting them to a fully new idea would be very cool to see.
