I like that you made such an extensive mind map. I can tell that you spent time and effort on creating it. I think its important to sit down and actually work exclusively on the mind map because it really gets the creative juices flowing.
I wish that you would have put little descriptions next to each of your sketches. It’s really nice that there are sketches and a title, so why not add a description? I think that would solidify exactly what your concept is.
What if the pipe inhaler was part of a whole line of “disguised inhalers”? There could be a cigarette shaped one, as well as, a sucker and lipstick. I really like your idea to make inhalers camouflaged, and a whole line would make for many more options.
