Exhibition Poster: Design Development

Here is my design development work for the exhibition poster. My main ideas centre around the words 'React' and 'Exhibit A', but I am struggling to come up visuals for a third concept, although I have thought of the words 'initiate' or 'assemble'. In terms of visuals, I want the posters to be bold and simple, so that they have immediate impact and appeal more to everyone who will see them. Simple visuals have also worked because I have not had much time to create designs for the concepts, and I would like to have completed them by the end of the week. I now need to develop some concept boards to present for the crit tomorrow.
