Imagepanel BBQ design

After some explanation from out teacher about how to communicate different aspects of our product with design I've made an imagepanel to show people what I want to communicate with the design of my barbecue.

What I am trying to get across is that my product will be lightweight, compact and easily portable. I feel like I can achieve this by making my design rectangular with rounded edges, using one single color for the entire product. If I were to add multiple colors, my product would appear cheap because of the simple shape.
