Progression of poster

I have added more company names down the bottom of the poster as I believe it makes the poster look more professional, I have also made another version with a different layout, I have also changed the font for the date which I have used. I have changed it to a more scratchy-looking title, this gives the poster a rough edge which will grab the audiences attention. I am going to ask around on which layout people believes looks more professional, I will consider other peoples opinions to improve my poster.
