Thank you to everyone that responded to my last post. I have attached 3 pictures of my initial designs. I have tried to make each of my designs solve at least one of the problems that I was told about, however once I have developed the designs they should solve most if not all of the problems. It would be a real help to me if you could look through my designs and tell me which three you like the most and why. Also if you want to suggest any improvements that would be helpful to.
