Poster for Presentation

So tomorrow is presentation and I have to print this poster design in order to present my retail store to the class. This is nothing flash due to the fact that I have edited each of my images, and designed my poster in an afternoon / night but it will be enough to at least gain critique on to know what works and what doesn't within my design. All I have to do now is go down to the Toy store and use the large format printer to print my poster at A0 size..
