Design Models

Today at tech with Mrs Ferguson we have been making models of phones stands. We used plastecine. I thought of different designs to create phone stands. I done three models. My favourite model was the hear one because I thought it was cool. How does this design support my phone? It supports it by holding the phone to make sure it won't fall forwards. I think out of all the phone stands Alex's chair case is the most smartest and coolest. How can you improve it? I would improve it by making my case look more better by molding it properly.
