For this project we had to create two examples of a web ad using the styles and dementions provided by IAB. The first  is billboard size. It was really hard to find some suitable images that didn't pixelate badly when resized however I think it will not be too bad due to the size of the ad when viewed on a small screen. I used a cloud background with a radial gradient and a stencil font to give it a military feel. Due to the size of the slider ad UI only used one plane image so as not to make it appear too crowded.
